Let's, denote the number of beat groups in measure m by Gm, the number of beats in beat group g of measure m by Bmg and the number of sub-beats in beat b or beat group g of measure m by Smgb.
If the number of beat groups in a measure is the same regardless of measure, we'll write either G* or just G. Similarly, we can say things like B*g if B varies by beat group but not measure.
We'll similarly use this * notation with T if possible.
All still true but we'll also use the * notation with t as well.
