Why you speed up and slow down while playing guitar

Symptom checklist

• playing gradually speeds up
• guitar tempo keeps slowing down
• cannot keep a steady tempo without a backing track
• start in time but drift away from the beat
• rush easy parts and slow down in difficult parts

Symptoms

You begin at the intended tempo, but after several bars you are noticeably ahead of or behind the beat. The change may be gradual enough that it feels normal while you play. It becomes obvious only when a backing track reaches a chord, accent or section before or after you do.

A common pattern is to rush familiar or physically easy material and slow down when a difficult chord change, string crossing or fingering approaches. You might also keep reasonable time within each short phrase but leave slightly too much or too little space between phrases. Those small differences accumulate until the whole performance has shifted.

This is different from one uneven strum, a late hammer-on or two hands arriving separately on a note. The defining symptom is movement of the overall pulse across several beats or phrases, even when most individual notes sound correct. Fender notes that players tend to speed up and slow down and recommends a metronome as a steady reference (source).

Causes

Tempo drift often begins when attention moves away from the underlying beat. You may be concentrating on remembering the next chord, reaching a difficult note, reading notation or correcting a small mistake. The hands then follow the immediate task rather than a continuous pulse.

Another cause is practising passages only from beginning to end. This can hide the exact transition where the tempo changes. Easy sections become associated with extra momentum, while demanding sections become associated with hesitation. Repetition then strengthens both reactions.

Your chosen tempo may also be too fast for consistent control. Being able to complete a passage once does not mean every transition is secure enough to fit the same pulse repeatedly. Finally, relying on foot tapping without checking it can be misleading. Your foot and hands may drift together, creating the impression that the beat remains steady.

Diagnosis

Choose a passage lasting at least 30 seconds and set a metronome to a comfortable tempo. Count one, two, three, four aloud for two bars before playing. Continue listening to the clicks rather than treating them as a count-in that disappears once you start.

Record one attempt. On playback, identify the first point where your notes begin landing consistently before or after the click. Do not merely judge the ending. Write down the bar, chord change or phrase where separation first becomes audible. Metronome practice is useful for establishing tempo and exposing trouble spots, particularly when the music is first played slowly (source).

Next, simplify the passage. Play only muted strums or one repeated note while preserving its rhythm. If the tempo still drifts, the main problem is pulse control. If the simplified version stays aligned, restore the original notes in small groups. The point where drift returns is probably a technical or memory demand that is disrupting an otherwise workable pulse.

Also test the difficult group by itself, then include one bar before and after it. This distinguishes a local mistake from gradual whole-performance drift.

Fixes

Lower the metronome until you can play the entire passage without chasing the click. Use a tempo that feels almost uneventful. Repeat it cleanly several times before increasing by a small amount. A gradual increase is more useful than jumping straight back to performance speed (source).

Practise the transition where drift first appears, not only the most difficult notes after it. Loop one bar before the change, the change itself and one bar after it. Count aloud and keep the motion continuous through the boundary.

For rushing, deliberately feel the space between beats. For slowing, reduce the fretting or picking demand: use smaller movements, prepare the next shape earlier, or temporarily omit non-essential notes. Restore the full part only when the reduced version remains steady.

You can also make the external pulse less frequent. Once ordinary click practice is reliable, set the metronome so the click represents beats two and four, or one click per bar at a suitable slow setting. Berklee identifies maintaining a steady pulse and working with varied metronome placements as ways to develop internal pulse and rhythmic accuracy (source). Return to clicks on every beat if the wider spacing causes guessing.

Mistakes

Do not respond to drift by forcing your hands to play faster. If the click seems to move away, first stop and determine whether you were rushing or dragging. Chasing it mid-passage often creates a sudden correction rather than stable time.

Avoid raising the tempo after one successful attempt. One accurate run may be accidental. Require several controlled repetitions, including a fresh attempt after a short break.

Do not turn the metronome so loud that it masks your attacks. You need to hear the relationship between click and note. Conversely, do not ignore the click whenever the passage becomes difficult.

Finally, avoid restarting after every minor wrong note. Sometimes continue with the pulse and rejoin at the next clear beat. This tests whether one error causes the entire performance to lose time.

Progress

Measure progress with repeatable recordings. Use the same passage and tempo, and note where drift first becomes audible. Improvement may mean reaching bar 16 before drifting instead of bar 8, reducing the size of the separation, or completing three consecutive steady attempts.

Check both an easy and a demanding passage. The easy one tests your underlying pulse; the demanding one shows whether technique still pulls the tempo around. Revisit them without a backing track, then confirm the result with the metronome.

A useful final test is to play for a minute with the click sounding less often, then return it to every beat. If you remain aligned without a hurried correction, your internal pulse is becoming more dependable. Keep tempo increases modest and preserve the same standard: the whole passage should stay with the beat, not merely begin and end near it.
