In the indicated measures in the following songs, there are expression marks placed away from the notes. Are these Expressions Executed during Sustained Notes and should they be transcribed as indicated in 2015 MBC 18.104.22.168?
In Tree of Peace, measure 15, I would use an in-accord with transcriber-added rests to show the crescendo beginning on beat 3 and ending after beat 4. In measure 18 an in-accord isn't necessary. The decrescendo can come before the first note and the piano before the quarter rest.
In 1941, the lower parts should use an in-accord to show the decrescendo beginning on beat 3. A termination of this decrescendo would not be necessary.
