Three steps to exploring the wonders of tempo shifting.
Hello and welcome back to another Dojo. This time I’m going to be talking about the joy of using varispeed in your tracking productions to give your music a different timbral shift and open you up to some very creative possibilities.
Varispeed is essentially a way of controlling pitch by adjusting playback speed. In pre-digital days, turntables and tape machines used different speeds for both recording and playback. Turntables had three speeds: 78, 45, and 33 1/3 rpm, and pro tape machines had three standard choices for starters: 7 1/2, 15, and 30 ips. In essence, if you record a fast passage at a slow speed, once it’s played back at normal or standard speed the pitch and tempo will go up. We’ve all heard the chipmunk effect—high pitched, helium-tinged vocals achieved by recording at a slow speed and playing back at normal speed. But there are more interesting and subtle ways to use varispeed.
My three favorite examples are Les Paul’s “Caravan” (on 1950’s The New Sound), the piano solo played by George Martin on the Beatles’ “In My Life” (Rubber Soul), and the Beatles’ “Rain,” the B-side of “Paperback Writer” (which is my favorite single the Fab Four released). The first two examples use varispeed on various tracks within a normal-speed mix. With “Rain,” however, the entire mix was shifted down in pitch (and tempo) after it was recorded at a faster tape speed! It was also the first Beatles song to feature reversed vocals, which occur at the end. For fun, try singing along with this song and you’ll feel like you’re in audio quicksand. It’s almost impossible to match Lennon’s words exactly because all your consonances will have to be slower than normal.
With old school varispeed, pitch and speed (transients and tempo) are tied together.
I want to make a distinction here: It’s important to know the difference between time stretching (changing the duration or speed of an audio signal without affecting its pitch) and pitch shifting (changing the pitch without affecting the speed). With old school varispeed, pitch and speed (transients and tempo) are tied together. This means the transients, formants, and overtones of all recorded material (an instrument, a vocal, or even a mix) are shifted. Which leads to an intriguingly unnatural sound, not possible in the real world. How can we do this in our DAW? For starters, make sure your DAW of choice has a varispeed function or setting. I’m going to show you how I do this in Universal Audio’s LUNA (which is free with an interface hardware purchase).
We need to do some prep work to start. Let’s assume you are recording a guitar/vocal at 100 bpm in the key of E (try singing and playing a 16th note palm-muted rhythm part on your guitar). Now, do the same thing again, but make a “varispeed” version of it by speeding the tempo up and playing/recording it in a new key. You can compare the differences when done. That should help your ears adjust to the concept.
Before you begin, calculate the transposition to tempo ratio. I use a great app on my phone called musicMath ($5.99 street) to do this. For this example, to transpose up a minor third (from E to G) the new tempo is 118.92 bpm [Fig.1].
Next, change the tempo in your DAW to 118.92 bpm, and then play/sing it again in the key of G (up a minor third) [Fig.2]. If you’re not sure where the chords are in the new key, use a capo at the 3rd fret and play the same chords you’ve been playing. Personally, I like playing without a capo because the voicings are different and the sound will be as well. More fun!
Now, render/bounce the new performance and import it back into your DAW session. Next—following the cue of “Rain”—enable the varispeed function in your DAW [Fig.3] and change the tempo to 100 bpm. If you look at what I’ve circled, you’ll see that the mode is set to “tempo” and the warp is set to “varispeed.” Your particular DAW may be different, so make sure your speed/tempo and pitch are linked. Otherwise, when you slow the tempo back down to 100 bpm, the recording will still be in the key of G, but slower. As usual, I invite you to come to bryanclarkmusic.com to watch this technique in action. Have fun and try this on everything! Until next month, namaste.

PRS Guitars celebrates 40 years with the limited edition McCarty SC56. Featuring vintage-inspired design and modern innovations, this single-cutaway guitar pays tribute to Ted McCarty and his impact on the industry. With only 400 pieces available, this instrument is a must-have for collectors and performers alike.
PRS Guitars today announced the 40th Anniversary McCarty SC56 Limited Edition. With a classic PRS single-cutaway body shape and carefully chosen specifications, the McCarty SC56 is both a tribute to tradition and a reliable tool for the modern performer. Only 400 pieces will be made.
“The SC56, signifying Singlecut and 1956, model is our most recent tribute to my late mentor Ted McCarty and his impact on the guitar industry. We started with our take on a classic late ‘50s singlecut body. 1956 marks the year that Ted first had guitars made with his newly coined 'humbucker' pickups. It also happens to be the year I was born. Bringing vintage design into the modern era, we loaded this model with our McCarty III pickups, meticulously designed to deliver warm, clear, vintage tone with exceptional note separation and dynamics,” said PRS Guitars Founder & Managing General Partner, Paul Reed Smith.
Anchored by a maple top and mahogany back, the 24.594” scale length and 22-fret Pattern Vintage neck work with Phase III non-locking tuners and PRS two-piece bridge to promote its musical sustain. The PRS McCarty III pickups are controlled by a simple layout — two volume controls, two tone controls, and a three-way toggle on the upper bout.
Single-cutaway guitars are known to be heavier than their double-cutaway counterparts. The McCarty SC56 Limited Edition design incorporates weight-relief, decreasing the weight of the guitar by about 2/3 of a pound, while maintaining several points of attachment between the guitar top and back to eliminate the “hollow” sound of the cavities and promote tone transfer.
With appointments like binding on the fretboard, classic bird inlays, and a vintage-inspired nitrocellulose finish, the 40th Anniversary McCarty SC56 Limited Edition blends heritage and innovation into a timeless instrument.
PRS Guitars continues its schedule of launching new products each month in 2025.

His credits include Miles Davis’ Jack Johnson and Herbie Mann—next to whom he performed in Questlove’s 2021 documentary, Summer of Soul—and his tunes have been covered by Santana and the Messthetics. But it’s as a bandleader and collaborator where Sharrock cut his wildest recordings. As groundbreaking as Sharrock’s music could be, his distorted tone and melodic tunes helped bring rock listeners into the jazz tent. Our callers let us know how much Sharrock meant to them and why he’s one of the “top guys of all time.”
Belltone Guitars has partnered Brickhouse Toneworks to create a one-of-a-kind, truly noiseless Strat/Tele-tone pickup in a standard Filter’Tron size format: the Single-Bell pickup.
The Single-Bell by Brickhouse Toneworks delivers bonafide single-coil Strat and Tele tones with the power of a P-90 and no 60-cycle hum. Unlike typical stacked hum-cancelling designs, Brickhouse Toneworks uses a proprietary ‘sidewind’ approach that cancels the 60-cycle hum without sacrificing any of the dynamics or top-end sparkle of a Fender-style single coil.
Get the best of both worlds with clear bell-like tones on the neck pickup, signature quack when combining the neck and bridge pickups, and pristine twang in the bridge position backed with the fullness and power of a P-90. Push these into overdrive and experience the hallmark blues tone with plenty of grit and harmonic sustain — all with completely noiseless performance.
Key Features of the Single-Bell:
- Cast Alnico 5 Magnet, designed to be used with 500k pots
- Voiced to capture that signature Fender-style single coil tone without the 60-cycle hum
- Lightly potted to minimize squeal
- Made in the USA with premium quality materials
The retail price for a Bridge and Neck matching set is $340.00 and they’re available directly and exclusively through Belltone® Guitars / Brickhouse Toneworks at belltoneguitars.com.
