Playing fast is one thing. Playing in time while changing speed — shifting gears between subdivisions mid-phrase — is an entirely different skill, and it’s one of the clearest markers of a mature, musical player. This lesson targets that skill directly.
What you’ll get out of this lesson: You’ll develop the ability to gear-shift cleanly between eighth notes (semiquavers) and triplet eighth notes (triplet semiquavers), training your fretting hand to stay rhythmically locked-in even when the subdivision changes beneath it.
What Gear-Shifting Actually Means
When you listen to great players improvise, they move effortlessly between different rhythmic feels — a phrase in straight sixteenths, then a triplet burst, then back. That’s gear-shifting: the ability to change subdivisions accurately and without losing the pulse. Most players practise each subdivision separately, which is fine, but never practise the actual transition between them. This exercise fixes that.
The Two Licks
The first lick is played in eighth notes (semiquavers) on the G string: 5–7–9–7, repeating for one bar. Count it as: one and two and three and four and. The second lick is the same idea but in triplet eighth notes (triplet semiquavers): 5–7–5–7–9–7, again for one bar. Count that as: one-and-a, two-and-a, three-and-a, four-and-a. Your goal is to go between those two licks seamlessly — one bar of the first, one bar of the second — with the transition feeling perfectly natural.
Why Slow Tempos Are Harder
This exercise is harder at slow tempos because there’s nowhere to hide. A gear-shift that “works” at 120 BPM might actually be slightly rushed or dragged — you just can’t hear it as clearly at speed. Start slow, count out loud if necessary, and make the subdivision change feel inevitable rather than effortful. The accuracy you build at 70 BPM carries over to 140 BPM far more reliably than the reverse.
Expanding the Exercise
Once the basic two-lick gear-shift is clean, practise the same concept on different strings and with different fingering combinations — try 1–3–4 or 1–2–4 instead of the default shape. Then push the tempo: the goal is always clean subdivisions first, speed second.
Your goal is to get that to where you just play each one once. Practise that on all strings. On different fingering combinations. And then practise it at different tempos, make sure the subdivisions are perfect.
Taking it further: Once eighth notes and triplet eighths feel natural to switch between, try introducing a third subdivision — 32nd notes or quintuplets — as a third gear. The principle is identical; it’s the number of subdivisions that changes, not the underlying beat. This kind of rhythmic flexibility is what gives improvised lines their sense of control and intention.
Your homework: Set a metronome to a slow, comfortable tempo. Play one bar of lick 1 (eighth notes, 5–7–9–7), then one bar of lick 2 (triplets, 5–7–5–7–9–7), back and forth for five minutes. Count out loud or tap your foot on the beat. Once that’s clean, raise the tempo by 5 BPM and repeat.
