Odd meters are easier to count once you know how long the bar actually is. This gives bar and note durations, and the cycle length where a cross-rhythm resolves.
Run it with your own numbers.
Odd meters are easier to count once you know how long the bar actually is. This gives bar and note durations, and the cycle length where a cross-rhythm resolves.
Bar and note length
Sixty over the tempo gives one beat in seconds; multiplied by beats per bar it gives the bar. Subdivision divides the beat again. Everything on this page follows from those two divisions.
Where the cycle closes
Two groupings realign after their lowest common multiple of beats. That figure is why a seven-against-four figure takes so long to come back around, and knowing it in bars makes the passage countable.
Timing is not feel
These are the durations a metronome would produce. Where the accents fall inside the bar, and how the grouping is actually felt, are musical decisions the arithmetic knows nothing about.
Real questions, short answers.
Which number is the beat in a compound meter?
Whichever you are counting. Enter the beats you actually count per bar and the subdivision inside them, and the figures follow your counting rather than the notation.
Why does the cycle figure matter?
Because it tells you how many bars to loop when practising a cross-rhythm. Looping fewer never resolves; looping more repeats.
Can I use this for delay times?
The subdivision figure is in milliseconds, so yes, though a dedicated delay calculator will be more direct about it.
