Thirty-Second Notes: How to Count, Play & Practice
A thirty-second note lasts one eighth of a beat, so eight fit in a single beat and thirty-two fill a bar of 4/4.

Thirty-Second Notes Explained
A thirty-second note (demisemiquaver) lasts one eighth of a beat in 4/4 time, with eight fitting into a single quarter-note beat. These extremely fast note values appear in virtuosic passages, ornamental runs, and dramatic flourishes. They require exceptional technique and are typically encountered at moderate tempos where the absolute speed remains manageable.
How to Count
At slow tempos, subdivide each sixteenth note in half, effectively counting eight even pulses per beat. Most musicians do not vocalize thirty-second notes individually at performance tempo; instead, they internalize the subdivision by practicing slowly with a metronome set to the sixteenth-note level, then gradually increase speed until the passage flows evenly.
Thirty-Second Notes in Real Music
Thirty-second notes are almost never the main rhythm of a piece. They appear as bursts: a flourish, a cadenza, a written-out ornament, a drum roll. In the Grave introduction to Beethoven's Pathetique Sonata, the slow dotted chords are repeatedly answered by extremely rapid runs, and the contrast between the heavy pulse and those fast flurries is the whole dramatic point. Chopin writes ornamental filigree the same way, letting a nocturne melody dissolve into a cascade of tiny notes before settling back onto the beat. Percussionists meet thirty-seconds constantly, since a measured double-stroke roll in a concert band or drum corps part is often notated exactly that way. Flamenco guitar picado runs and virtuosic jazz solo lines reach the same density in bursts rather than for whole choruses. The performer's note is that thirty-second notes should be practised as groups, not as individual notes. Because they usually fill a single beat or two, the reliable approach is to learn the whole flurry as one gesture that starts and ends on a known beat. Set the metronome slowly, around 30 to 46 BPM, and count each beat as eight even notes; anchoring the first and last note of the run matters far more than the ones in the middle. If the run ends on time and sounds smooth, it will read as brilliant even at moderate speed.
Common Mistakes
- Playing thirty-second notes as an uncontrolled burst of speed rather than precisely timed subdivisions.
- Neglecting the slow-practice phase and trying to play them up to tempo immediately, which embeds unevenness.
- Confusing thirty-second-note passages with grace notes or ornamentation when they are actually measured rhythms.
Practice Exercise
Set a metronome to 40 BPM. On a single pitch, play eight notes per beat (thirty-second notes). Focus on absolute evenness, each note should be identical in volume and spacing. Record yourself and listen back for any irregularities. Gradually increase to 50 BPM over several days.
Suggested metronome tempos: Slow: 30 BPM · Medium: 46 BPM · Fast: 66 BPM

FAQ
How fast are thirty-second notes?
At 60 BPM, a thirty-second note lasts just 125 milliseconds, eight notes per second. At faster tempos they become even shorter, which is why they usually appear in slower passages or brief bursts.
When are thirty-second notes used?
They appear in virtuosic solo passages, cadenzas, fast scalar runs, and dramatic flourishes. They are most common in classical, flamenco, and metal music where technical speed is a defining feature.
How many thirty-second notes are in a bar of 4/4?
Thirty-two, because each of the four beats divides into eight thirty-second notes. That is twice as many as the sixteen sixteenth notes that fill the same measure.
What is the difference between thirty-second notes and triplets?
Thirty-second notes divide the beat into eight equal parts using ordinary binary subdivision. A triplet divides one beat into three equal notes, a grouping that does not exist in the standard halving sequence and is marked with a 3.
How fast should I practice thirty-second notes?
Start at about 30 BPM so each beat unfolds as eight clearly separate notes. Move to 46 BPM when the group sounds even, and treat 66 BPM as a demanding target rather than a starting point.
