So, I ran into a bit of an issue related to time signatures. In this orchestral piece I am working on(still writing down the piano solo version but I am thinking about the orchestration every step of the way). Namely, that the downbeat moves from the strongest beat in 4/4 to the weakest, from beat 1 to beat 4 when a solo starts in the bass clef. If the downbeat moved to beat 2, I would be thinking:
Well, that is just a bit of syncopation, no worries. The beat will move back to beat 1 after the solo.
But, the downbeat moves to beat 4 when the C is reached in the bass clef melody(at least, that's what I hear in the recording of my piano improvisation). And beat 4 is the weakest of all the beats in 4/4, usually being the upbeat. I am contemplating perhaps inserting a 3/4 bar just before the accompaniment for the solo comes, so that the downbeat matches up with beat 1 again. Here is the solo unaltered:
If I insert a preceding 3/4 bar at bar 70 and then immediately change back to 4/4 at bar 71, the downbeats match up with beat 1 once again. But, this leaves me with an extra beat and since the downbeat is on beat 1 after the solo, when it changes to 2/4 for a second dramatic outburst, that means that the final bit of arpeggio is going to have to end on beat 4, which means a rest between the supposed end of the arpeggio and the actual final bit of arpeggio, given that the arpeggios are 16th notes. Now, I mean, that is what I do in the recorded piano improvisation, but I have quite a few pauses in the recording that aren't representing rests.
Wait a second, it sounds to me as though the downbeat moves back to beat 1 at the whole note C. A 5/4 bar in the form 2+3. But then, the final bit of the arpeggio would again be 3/4. That would mean this time signature sequence:
Bar 70: 3/4 Bar 71: 4/4 Bar 73: 5/4 Bar 74: 4/4 Bar 75: 3/4 Bar 76: 2/4
And that is just to match the downbeat with beat 1 during the solo. Wow is that a lot of consecutive time signature switching. At least it is gradually adding and subtracting beats to the bar and this excerpt is from the second slow section but still, that's a lot of time signatures in quick succession. And the sixteenths won't beam right in the 5/4 in Musescore. I have run into that issue every time I write in 5/4, that the beaming does not look right.
I would like to keep it in 4/4 if I can to avoid the six time signatures in quick succession. But then, if I am keeping it in 4/4, how would I get across that the downbeat changes to beat 4 at bar 70 and then back to beat 1 at bar 74? Dynamic accents?
