Enter the notes per beat and the tempo into the Calculator. The calculator will evaluate the Notes Per Second. 

Notes Per Second Formula

NPS = NPB * T / 60


  • NPS is the Notes Per Second (notes/sec)
  • NPB is the notes per beat
  • T is the tempo

To calculate Notes Per Second, multiply the notes per beat by the tempo, then divide by 60.

How to Calculate Notes Per Second?

The following steps outline how to calculate the Notes Per Second.

  1. First, determine the notes per beat. 
  2. Next, determine the tempo. 
  3. Next, gather the formula from above = NPS = NPB * T / 60.
  4. Finally, calculate the Notes Per Second.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

notes per beat = 30

tempo = 4


What is the significance of calculating Notes Per Second in music?

Calculating Notes Per Second (NPS) helps musicians and composers understand the density of notes in a piece of music, allowing for better control over the pacing and energy of the composition.

How does tempo affect the calculation of Notes Per Second?

Tempo, measured in beats per minute (BPM), directly influences the NPS. A higher tempo increases the NPS, indicating a more densely packed sequence of notes, while a lower tempo decreases the NPS, indicating a more spaced-out sequence of notes.

Can the Notes Per Second formula be used for any type of musical notation?

Yes, the NPS formula is versatile and can be applied to any musical notation where the tempo and notes per beat are known, regardless of the musical genre or the complexity of the piece.

Is it necessary to use a calculator for finding Notes Per Second?

While the calculation can be done manually, using a specialized calculator like the ones mentioned on the page can simplify the process, especially for complex pieces of music or when working with irregular tempos.
