Hi all, my first post here. :) Recently I was given the music of a song that our choir is working on, and I was asked to make an arrangement as the backing for our performance. The song starts off in 3/4 timing but during the chorus it switches to 9/8, then back again to 3/4 later on. I understand that 9/8 is like playing each beat of a 3/4 bar in triplets. My concern is with the actual duration of each note(quaver) and consequently each bar. Some members of the choir maintain that the notes in the 9/8 section should be played with shorter durations so that the overall bar would last the same as in the 3/4 sections of the song(effectively played as 3 x triplets in each bar). Others seem to think that each note should still keep their original duration, resulting in each bar lasting 50% longer in real time(9 quavers = 4.5 crotchets = 150% of a 3/4 bar). I myself am tending to agree with the later but not 100% sure and would appreciate some clarification. Hope I have made myself clear here. Thankyou all in advance.
