Time lines (brackets)

Time lines (also known as "brackets") are used to indicate a variation in a repetition of a phrase or measure. A timeline should indicate what needs to be played the 1^st time through (indicated with a 1), and another time line should indicate what to play the 2^nd time through. The 2^nd time through can be indicated with one of the following:

2: 2^nd time through

2 of n: 2^nd time through of the n^th part, e.g. 2 of 2 (2^nd time through of the 2^nd part)

2 of n and m: 2^nd time through of the n^th part and 2^nd time through of the m^th,part, e.g. 2 of 2 and 4 (2^nd time through of the 2^nd part and 2^nd time through of the 4^th part)

For example, Jenny's Bawbee's 2^nd part play 1^st time as written, and 2^nd time through play time line 2 (in the 1st part) instead of time line 1.
