The first triplet is very uneven. Its total length is 1/4.
Triplet 1:
A (1/8), D#(1/4), F#(1/4 divided by 3 = 1/12)
For how long should I hold A and D#? Should I hold D# with 1st finger until C# from the 2nd triplet is pressed with the 2nd finger?
Or just together with F#:
Triplet 2:
C# (1/4), F#(1/12), A(1/12)
Here I keep pressing C# with 2nd finger while playing F# (4th), A (5th)
Triplet 3 (simple):
I hold B# till the end of this triplet and the next one.
Please, explain, how to play the 1st triplet?
