Most siddurim (Nusach Ashkenaz Sefard) group the shofar blowing as follows:
- 30 blasts before Musaph divided as:
- A 3 times Tekiah Shevarim-Tru'ah Tekiah
- B 3 times Tekiah Shevarim Tekiah
- C 3 times Tekiah Truah Tekiah
1 time of each group A, B and C from above. Each one done at the end of each of the 3 middle sections of Shmoneh Esreh - chazan's repetition.
repeat of procedure that was done before Musaph + procedure used during musaph.
Is one allowed to break up this sequence in any way? E.g. can he do only groups A and B and leave C for after Musaf to add on to the others?
If one is allowed to break things up, must he have at least a group of 10 in the format:
Tekiah Shevrim Truah Tekiah Tekiah Truah Tekiah Tekiah Tru'ah Tekiah
Or can he do less than 10 at a time?
If he is not allowed to divide anything from what the siddur's format (say he must do all 40 at once as indicated), what if he has an "emergency" and is short of breath. Can he finish the rest later, or must he find someone else to complete the group for him at that time?
