Get Bar count from Time and Tempo

Need to calculate the number of bars in a piece of recorded music?

Use a metronome (I use the Metrotimer App ) to get your beats per minute. Derive the total time from the time counter numbers in iTunes or another playback app (or use a stopwatch! Old-style!)

The time signature is almost always going to be “4” these days – until the Waltz comes roaring back into fashion…
