The Music Duration Calculator computes:
- Duration of Music based on it's tempo, time signature and number of bars
- Tempo of Music based on the duration, time signature and number of bars.
What is the use?
- If you are composing music, this could be useful for determining the length of your song. It is handy for recording or when performing.
- Determining how fast or slow you have to play a song is crucial for instances like playing a soundtrack over a video or playing a song for a limited slot time.
Instructions
The calculator has two buttons. One to compute Music Duration, and one to compute Music Temp.
To find the Music Duration, click on the Duration button enter the following:
- Tempo (for example: 112 bpm)
- Number of measures (this could be found by counting the amount of bars from sheet music perhaps).
- Number of beats per measure which is given by the top unit of the time signature.
Example: Tempo = 100 bpm, number of measures = 140, beats per measure = 4
length of song = `(4 x 140)/100 * (60 "seconds")/"minute" ` = 336 seconds or 5.6 minutes
To find Music Tempo, click on the Tempo button enter the following:
- Beats per measure
- Number of measures
- Length of the music segment
You'll just need to manipulate the inputs in relation to the tempo:
Tempo = beats per measure x number of measures x 60 seconds
length of song (in seconds) minute
