Song length calculator

Give the tempo and # of bars

Length of 1 beat

The length of a single beat is purely defined by the beats-per-minute (BPM) you chose.
  • Beats-per-minute: 120 BPM
  • Beats-per-second: 2 Hz
  • Length of 1 beat: 0.5 second = 500 msec
  • Length of 1 bar

    The number of beats in a bar or measure is defined by the time signature you chose.
  • [ ♩ ♩ ♩ ♩ ] : 4 beats in a bar (time signature is 4/4)
  • Length of 1 bar (4 beats): 2 second
  • Length of the song

    Now let's calculate the full length of the song
  • 48 bars = 12 phrases of 4 bars
  • Total song length is 96.000 secs = 1m 36s
