A/B Looping Practice Technique
The single most effective practice tool you're probably not using.
What A/B looping is and why it matters
A/B looping means setting two markers — A at the start of a section and B at the end — and having the playback repeat that section forever until you stop it. On the surface this sounds trivial, but it fundamentally changes how you practice. Instead of rewinding manually and losing focus between attempts, the same music plays continuously, giving you dozens of repetitions in the same time you'd normally get five. More reps with less friction is the entire game in skill acquisition.
Keep your loops short — 2 to 8 bars
The biggest mistake beginners make with A/B loops is looping entire sections — a whole verse, a whole chorus. Long loops mean fewer repetitions of any specific phrase, which dilutes the practice. The optimal loop length is 2 to 8 bars: short enough to get many reps, long enough to contain a complete musical idea. For especially gnarly licks, drop to a one-bar loop. Short loops = focus. Long loops = drift.

A/B looping and slow-down are a one-two punch. Looping alone gives you reps; slow-down alone gives you clarity. Combining them means you get many reps of a clearly-heard passage, which is the absolute ideal for learning. Start the loop at 50–70% speed, work until you can play along cleanly, then gradually increase speed. loope does both simultaneously with no setup friction — set A, set B, adjust the speed slider, play.
Use it for every stage of learning
A/B loops are useful at every stage, not just the beginning. Stage 1 (transcribing): loop the section you're figuring out. Stage 2 (practicing): loop the section you're drilling. Stage 3 (memorizing): loop the section you're internalizing. Stage 4 (performing): loop the section you're making expressive. Same tool, different purposes. Many pros have their A/B loops set up on dedicated pedals during recording sessions — it's not a beginner crutch, it's a universal tool.
Loop across transitions, not just within them
A subtle move: once you can play both of two adjacent sections, loop the transition between them. Set A in the middle of section 1 and B in the middle of section 2, so the loop crosses the seam. Transitions are where mistakes live, especially tempo changes and key changes. Looping the transition specifically drills the join, which is the part everyone gets wrong on stage. This is a pro-level use of looping that beginners rarely think of.

Frequently Asked Questions
Set A on the downbeat of the first bar of the section you want to practice, and set B on the downbeat of the bar *after* the last bar. This way the loop starts and ends on a natural musical boundary, not in the middle of a phrase.
In loope, yes — click a new A or B position while playing and the loop adjusts on the next cycle. This is great for zeroing in on problem spots without interrupting the flow.
A good looper plays seamlessly with no gap, so the section sounds continuous. loope is designed for this — the B-to-A jump is instantaneous, so you can practice as if the music never ends.
Drill until you can play the section cleanly three times in a row, then take a 30-second break or move on. Endless looping on autopilot is not useful — the brain consolidates best with short, focused bursts.
Briefly yes, during shedding. The workaround is to rotate between 2–3 songs per session so no single section saturates you. And remember: the boredom means you know it. Once you've overlearned it, performance-grade confidence follows.
