Leap year and drop-frame time code are conceptually the same

For those in the media production industries, February 29th is a good day to revisit drop-frame SMPTE time code, because both leap year and drop-frame time code came into being for the sole purpose of reconciling two different time bases on which we do things with mundane regularity.

Take the calendar first: our calendar simply charts the sequence of the individual days that comprise a single year. The day is based, of course, on a single rotation of the earth on its axis, whereas the year is based on a single revolution of the earth around the sun. Rotation and revolution are the two different time bases on which our calendar is constructed.

Since it takes about 365.25 days for the earth to revolve around the sun, we collect four of those quarter days and add them together into a single day—February 29—that appears on the calendar once every four years.

We do this because there's no such thing as a quarter-day: you couldn't start a New Year at 6:00 a.m. After all, a day is a day and cannot be partitioned like that. It's an integer.

It's important to see that the concept of the yearly calendar comprises 366 days—February 29 is not imaginary. But rather than adding it every four years, what we are really doing is dropping it from the calendar in every year that is not a multiple of four. If the year is not divisible by 4, then we drop February 29 from our count of days in that year.

It's exactly the same with drop-frame time code, where frames are analogous to days, and hours to years. A video frame is a whole thing, an integer, and we count 30 of them in one second. But the rate at which they proceed is a bit less than 30 per second, more like 29.97 frames per second.

This is the same sort of fractional discrepancy that exists in the annual rate of 365.25 days per year.

We deal with it the same way, by dropping 2 frames from the count at the very beginning of every minute that is not a multiple of 10. In that first second, there are only 28 frames.

So frames 00 and 01 simply do not exist at the beginning of every minute of time code that doesn't have a zero at the end of it (10, 20, 30, 40, 50, and 00 minutes being the exceptions), just as February 29 does not exist in any year that can't be divided by 4. It's as simple as that.

Why go to the bother of doing this? For the calendar, it's long been considered important that the seasons start at roughly the same time every year: if we didn't have February 29 as a corrective, then the beginning of Spring, for example, would progress steadily back through February, January, December, and so on as the years rolled by.

For producers, it's important that the time displayed by your time code reader agrees with the real-time clock on the control room wall. Without drop-frame time code, a one-hour program as measured by your time code would actually run 3 seconds and 18 frames too long, and that would wreak havoc with broadcast schedules.

Note that what we are NOT doing is cutting out frames from our program and leaving them on the cutting room floor, as some of my former students at the Toronto Film School used to believe. Those "dropped" frames are simply never there in the first place, just as February 29 will not "be there" in 2013, 2014, and 2015. The calendar works as "drop-day" code.

The takeaway from this blog entry is that if you can intuitively grasp the concept of leap year, then you've already got the essence of drop-frame time code. Conceptually, they are one and the same.

Seller Beware—When You're Being Shopped for a Price

I got an email last week asking how much I would charge to mix 5 songs for a band's EP. I wrote back asking whether I'd be recording the original tracks, or just mixing tracks that someone else has already recorded for the band. Both, came the reply, and how much would it cost?

I wrote back to ask about the band, number of players, what instruments, etc., so that I could price out the job using the appropriate recording facility, and asking for a couple of possible dates when the band wanted to start recording. This is an important question, because in sales, there's a strong relationship between price, availability and delivery. You can sometimes get a better deal on studio time that would otherwise remain unbooked.

At this point, the answers started to get vague. What was clear, however, was that I was being shopped for a price. In other words, the prospect (not yet a client) had no intention of coming to me for the job, but was only trying to get a handle on the price of a job that most likely he was bidding on himself.

This happens to everyone from time to time, and is one of the reasons why it's not a great idea just to shoot out a price in response to an inquiry. Every job is different in some way, and a big part of the sales process is asking questions to qualify the buyer.

Asking questions not only keeps valuable business intelligence—your pricing policies— out of the hands of your competition, it also saves you from wasting time with tire kickers who would otherwise take up a lot of your time, but never end up buying anything.

The 80-20 rule seems to apply here: 80% of your business comes from 20% of your prospects. This is further refined so that in turn, 80% of your income comes from 20% of them. In other words, 4% (20% of 20%) of your potential clients are responsible for about two-thirds (80% of 80%) of your business.

Asking questions is your best line of defense here, and a genuine prospect will appreciate that you're drilling down in order to provide the best possible service.

MIDI Orchestration

I've just finished a first read-through of the 4th edition of Paul Gilreath's The Guide to MIDI Orchestration, published by Focal Press. Coming in at 600 pages, it's a pretty thorough introduction to the subject of orchestrating a musical composition using MIDI-based equipment and instrument sample libraries.

Several topics of interest to non-MIDI orchestrators and project studio folks alike are covered here, including instrument ranges and playing techniques, notation, voice leading, distribution of melodies and accompaniments to different instruments in the various sections, combining instruments to create different sounds, and achieving specific moods with orchestrations.

For the MIDI producer, there's a wealth of information on equipment, software, choosing sample libraries, and sequencing strings, woodwinds, brass, percussion, piano, harp and voices.

The author illustrates portions of the text with screenshots from his favourite digital audio workstations: Cubase/Nuendo, Logic, Digital Performer and Sonar. Unfortunately, Gilreath dismisses ProTools, saying it's "still working to catch up" in this area, which is too bad, given its market penetration together with the strides that ProTools has made in the whole area of MIDI sequencing and sampling since version 8 was released at the end of 2008.

In any event, readers working with ProTools can easily adapt the material to their way of working, which, in most respects, is not too different from the others.

Supplementary material is available online at www.midi-orchestration.com, including reviews of several good instrument sample libraries, supplementary tutorials, and audio examples, but you have to sign in to access it.

Much of this material—including several full-length, uncut chapters—is still freely available for download as a single zip file from Focal Press at www.focalpress.com/midiorchestrationfiles.aspx.

The book is a terrific reference, and it's refreshing that the author combines description and prescription in almost equal amounts, which is a rare feat. Anyone looking for a grounding in MIDI orchestration would do well to own this book, and will check in with it on a regular basis, if not frequently. It's a beautiful volume, well designed and easy to read, with a crisp and clear layout, and it should be on every music producer's reference shelf.

My criticisms are few. There are numerous errors relating to missing or misplaced illustrations or examples, including a missing reference section with bibliographical apparatus that the author himself refers to twice yet, strangely, is nowhere to be found!

There are also too many proofreading errors, not many of them spelling mistakes, which leads me to believe that spell-check may have served as a convenient substitute for a thorough proofing. This is a tad disappointing in a 600-page book priced at US$82.50 ($86.50 Canadian).

Fortunately, these shortcomings are overshadowed by the author's monumental achievement in turning out what was surely the crowning achievement of his career as a composer for film and television. May his new life as a dentist in Atlanta be as fulfilling!

Good Sound at the new Helzberg Hall in Kansas City

The $413 million Kauffman Center for the Performing Arts in Kansas City, MO, opened to delighted audiences on September 16 with performances by Placido Domingo, the Canadian Brass, and the Kansas City Symphony, among others. Designed by architect Moishe Safdie, the Kauffman Center houses the 1,600 seat Helzberg Hall, a terraced concert hall-in-the-round that is home to the Kansas City Symphony, and the 1,800-seat Muriel Kauffman Theatre that will serve as the performance home of the Kansas City Ballet and the Lyric Opera of Kansas City.

The two venues have been described as the yin and yang of the Kauffman experience—the exuberant Muriel Kauffman Theatre with its proscenium and illuminated acrylic balcony fronts ringing the hall stands in marked contrast to the sleek and ethereal oval-shaped Helzberg Hall, that some visitors have likened to the interior of a wooden ship, with its warm, muted wood tones that recall the Walt Disney Concert Hall in Los Angeles.

Noting this resemblance in both form and material, critic Steve Paul wrote in The Kansas City Star, “One important connection between these two concert halls was the work of Yasuhisa Toyota of Nagata Acoustics, whose choice of shapes, wood and physical components was paramount in creating the aural experience.”

Toronto consultants Engineering Harmonics worked with Nagata Acoustics in both Kansas City and Los Angeles, designing performance sound systems to integrate seamlessly with the natural acoustics. Judging from the critical acclaim that followed last month’s inaugural performances in Helzberg Hall, the result is a resounding success. The amplified sound is “ambient and natural-sounding,” wrote David Mermelstein in Musical America.

Paul added, “Insiders will argue whether Helzberg exceeds even Disney, a slightly larger hall, though time—plus word of mouth in the music community—will tell.”

“This was our second foray into the design of a sound system in a terraced hall with Nagata Acoustics,” noted Engineering Harmonics president Philip Giddings. “In Kansas City, we further developed and refined our approach to this type of venue, and we are more than encouraged by the response of performers, audiences and critics alike,” he said.

If your glass is more beautiful than the wine, change the wine

So says noted wine writer Tony Aspler.

Owners of smaller home and project studios who are tempted to hire top-notch professional recording engineers to help ramp up their business risk seeing clients follow these engineers to better studios.

I've seen this happen time and time again. Home and project studio owners need to understand that this is almost always inevitable when their reach starts to exceed their grasp and they want to compete with the big boys.

It may be prudent for smaller studio owners to consider a significant upgrade of their rooms and equipment before enlisting the services of established outside recording engineers.

It won't be the engineers' fault if clients seek to follow them to greener pastures.

When a studio won't release the tracks you've paid for

Songwriters and musicians who use the services of small, home-based studios—and, for that matter, established commercial studios—would be well advised to establish the terms, conditions and policies of the studio before undertaking any recording.

I’m writing this because a beginning songwriter has come to me for advice. He is having a hard time getting a home studio owner to release his tracks, even though he has paid his bill in full—over $13,000! The songwriter wants to take the basic tracks of three songs that he recorded at this particular home studio to another, larger commercial studio for editing, mixing and mastering, but the owner of the home studio is refusing to release the material.

By way of explanation, the home studio owner wrote to me saying that he is “not going to let him take the files out of this studio in the condition they are. How he is going to come up with a better mix than any one of our engineers is beyond me to imagine. The files simply aren't ready to be exported or given away. Many guitar and other instrumental parts remain unedited and comped so even if he wanted them they are in no condition to give away.”

(The songwriter has made it clear that editing and comping are among the tasks he wants to complete at the new studio.)

The home studio owner then goes on to say, “We are not willing to give the files out. This is not normal practice. If he really wanted the files he'd have to buy us out but at this time I am not willing to even consider this.”

I’m not sure I understand why the owner thinks that releasing tracks that have been paid for is not “normal practice.” It’s also not clear to me what he means about the songwriter having to “buy us out,” given that he paid his bill in full over six months ago!

The studio owner concludes, “If this project goes out of the studio I have no guarantee if it will be mixed to a certain standard and I've brought in some heavy players that [the songwriter] got at cost.”

Why the studio owner considers it his business that the songs will be “mixed to a certain standard” is beyond me. That is not his responsibility. And the part about providing players “at cost” seems to indicate that the studio owner is in the habit of marking up session players’ fees and then taking a piece for himself. Maybe that’s how the cost of three unfinished demos climbed to beyond $13,000!

This might never have become an issue if the songwriter had clearly established the ground rules at the outset. At this point, it looks like a case for small claims court.

Songwriters be warned: Make sure you know at the outset what policies, practices or procedures a studio considers to be normative before you record a single note there. Second, make it your business to pay session players directly. Don’t accept an all-in deal with the studio, where you pay everything to the studio. In fact, it should be your job—or your producer’s job—to hire the session musicians in the first place.

I know of one instance where a guitar player was unable to attend a session because his wife went into labour that morning with their first child. I was there when the studio owner actually called the rental department of a local music store (Long & McQuade in Toronto) to find an on-the-spot replacement. When the replacement guitarist arrived, it became painfully apparent that he couldn’t read the chart. In fact, he couldn’t even tune his guitar, and he was sent away with return cab fare paid by—you guessed it—the songwriter!

At that point, the songwriter should have called it quits, but he was too cowed by the studio owner to voice his displeasure.

My final recommendation is that songwriters should bring a USB drive—preferably 8 GB or 16 GB—to their sessions, so that they can take a backup of their recordings away with them—provided, of course, that their account with the studio is paid up to date. After all, possession of the recorded material is the only security a studio has against non-payment for services rendered.

I have not named the offending studio in this blog entry, but readers who wish to continue the discussion can email me at buzz@abcbuzz.com.

Sgt. Pepper at 44

June 1 marked the 44th anniversary of the release of the Beatles' landmark album, Sgt. Pepper's Lonely Hearts Club Band. Hailed by many as the first concept album, it was based on the seed of an idea that Sgt. Pepper's band, as the doppelgänger Beatles, could be sent out on tour instead of the Beatles as a way around the problem of their not touring anymore. At least that's the way producer George Martin remembers it in his book, With a Little Help from My Friends.

But it didn't quite turn out that way, as the Sgt. Pepper concept was soon abandoned after the title song (and its reprise) and the introduction of Billy Shears. As Ringo Starr said in a TV interview, "It was going to be a whole show, but after two tracks everybody started getting fed up and doing their own songs again."

I think the concept is a bit deeper than that: with Pepper, we are being invited into the fantasy that there is a band there at all—after all, it begins with the sounds of an expectant audience at a live performance. But Pepper is anything but live.

The Beatles invited us to imagine this band playing, then offered up all sorts of other imaginings, some more literal than others: "Picture yourself in a boat on a river"...Or that there is a 41-piece orchestra accompanying the band.

In 1967, the practice of overdubbing wasn't new, but what was new was the idea of replacing one of the most exciting live four-piece bands ever to take the stage with this time-shifted collection of takes and other sounds, and then offering the whole thing up as a performance, complete with introduction of a "band" (albeit a tongue-in-cheek fictitious one).

This was the revolutionary idea of Sgt. Pepper: the concept of the album as performance rather than the live show as performance, something the Beatles themselves no longer wanted anything to do with.

With Pepper, performance occurs at the moment of hearing, rather than the moment of execution. Indeed, in multitrack recording there is no single moment of execution. The work is time-shifted—in some cases even place-shifted—for every contributor and comped track.

By extension, the concept is also that there is a "band" there at all. In fact, the band—two guitars, bass, drums and four guys singing—had been winding down for some time. As George Harrison said on a plane back to London after their last concert in San Francisco a year earlier, "Well that's it, I'm not a Beatle any more."

Multitracking allowed the Beatles to perpetuate the fantasy of the band's continued existence. Multitracking on their albums wasn't new. It was there in the double-tracked vocals on their earliest albums, the addition of strings in Yesterday, and George Martin's keyboard contributions to Rubber Soul. But it began in earnest on Tomorrow Never Knows, the first track recorded for Revolver in the months just before they quit touring for good: "Turn off your mind, relax and float downstream..."

George Martin has said that this is one track that could never be reproduced live, or even mixed the same way, because of all the random movements of the faders made by 10 people during mixing and the relative positions of multiple tape loops all playing at the same time. And even though they were still touring at the time, "Revolver was the first album from which no song was ever performed...they couldn't do them on stage," Martin said.

But with Sgt. Pepper, the fantasy was made explicit, and the enthusiastic reception the album received immediately on its release showed that the world was more than willing to accept this revolutionary new model.

Sgt. Pepper ushered in a new paradigm of musical creativity along with a new era in rock, and helped launch an industry to bring this recording technology first to the studios and later to our homes, so that we could all participate in the conceptual fantasy of the recording-as-performance.

Forty-plus years later, the pendulum is finally swinging back in the other direction, as the bottom continues to fall out of the record industry and money drains away from recordings as articles of perceived value in and of themselves, and back toward live shows. The concept of the live show as the real moment of performance appears to be regaining centre stage.
