Well,
This may be how I might approach it:
The left hand is straight forward 3/4 time (1,2,3 etc), so use it as your scaffolding and fit the treble into it (each measure adds up to a total of 3 beats ).
Here's where the " ta te ta" system of reading beats comes in handy .
(Mine may be a little eccentric but it's the idea that counts
).
First measure treble:
Ta tateta tateta= ta ta ta (for the bass)
Second measure treble:
The A lasts for the whole measure (and for one beat into measure 3)
It is briefly joined for a beat each by F and E. So, begin by holding down the A (ta) then chiming in the F ( ta) let the F go and chime in the E (ta), end of measure ( keep hold of the A into the next measure because of the "tie":ta)
Third measure:
Holding the A, chime in the E flat and C (half a beat each: ta te).
Then play the triplet: tateta = one beat.
Then the final beat A and C half a beat each: ta te .
And so forth...
What may be helpful is something like:
French Time-Names System – Ta, Ta-Te
This is one of the earliest known systems for rhythmic training and was developed in the early nineteenth century in France. This system of rhythm reading was named the French “Time-Names system”, and also sometimes called the “Galin-Paris-Cheve system.” Originally notes were counted using a French word for a duration regardless of the meter. For example, “noir” (black) is said for each quarter note, two eighth-notes are “cro-che” (eighth-note), a half·note is “bla-anch” (white), and four sixteenth notes are counted “dou-ble cro-che” (double eighth-note). Taken together, any given simple rhythm can be spoken and then performed using these patterns easily and fluidly.
Toward the middle of the nineteenth century the American musician Lowell Mason (affectionately named the “Father of Music Education”) adapted the French Time-Names system for use in the United States. Instead of using the French names of the notes, he replaced these with a system that identified the value of each note within a meter and the measure."
I have a paperback book along these lines but I couldn't find it to cite it.
Being able to verbalise the beats from printed music I find very helpful .
