Don - what you wrote did remind me of a minor solution I had to my timing problem. I took a few of my pop music selections and rewrote the sheet music at half speed (using a program like MuseScore). It takes work, but it's fun for me because it immerses me in the music. What I do is rewrite the song in half-time, so eighth notes become quarter notes, etc. It doesn't mean I necessarily get the song up to the intended speed (since I'm slow!) but it does help me understand the timing better and get some more flow into the song.
It appears you have some mathematical skills.
The bottom line is .... whatever works.
Your solution reminds me of how I often deal with complex timing issues.
I work within a single measure at a time ....
I assign the smallest denominated note a value of ONE.
Then, every other note in the measue gets a RELATIVE VALUE related to that note having a value of one.
For example, if the note with the smallest denomination is an eighth note (having a value of ONE), then a quarter note gets a value of TWO because a quarter note is equal to TWO eighth notes.
A half-note would get a value of FOUR. etc ....
Then I add up all the values in that measure and that is how many TICKS I have to deal with and those TICKS have to take place within the number of BEATS in the measure and they must be evenly spaced in time.
Then, I must be able to "hear" those TICKS so I know how long to hold each note.
That will allow you to experience the relative timing of the notes in the measure.
I gets complicated to explain so I will stop.
However, if you understand, it will work for any combination of notes.
PS: Don - thank you for replying to my thread ("Shut down a few weeks"), and for the advice you gave me. I will look for a piece to make my masterpiece!
Thank You. Good to hear.
