How to Use This Calculator

Enter BPM, Note Value, and Dotted (0=No, 1=Yes).
Set Tuplet (0=None, 3=Triplet, 5=Quintuplet).
Review the Duration (ms) result.
Use Duration (sec) and Frequency (Hz) to inform your decision.
Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with BPM

BPM: The tempo in beats per minute.
Note Value: 1=Whole, 2=Half, 4=Quarter, 8=Eighth, 16=Sixteenth.
Dotted (0=No, 1=Yes): A dotted note adds 50% to its duration.
Tuplet (0=None, 3=Triplet, 5=Quintuplet): Tuplet grouping. 3=triplet (3 in space of 2), 5=quintuplet (5 in space of 4).
