Hey,
Figured it out:
t = (60/b) * 4m * s
Where:
t = time in seconds
b = tempo in BPM
m = number of measures
s = time signature
So, if you have a 4/4 song which is 16 bars long at 120 BPM, you would do this:
t = (60/120) * 4(16) * (4/4)
-
t = (.5) * (64) * (1)
-
t = 32 seconds.
If you have a 7/8 song which is 64 bars long at 106 BPM, you would do this:
t = (60/106) * 4(64) * (7/8)
-
t = (.57) * (256) * (.875)
-
t = 126.8 seconds (rounded)
There will be quiz tomorrow.
