Hi Bernhard,Thanks for your answer,
1) There are 4 voices on 2 staves. Ok, so some notation is to be sung by members of a Choir singing different note durations, is this right?
2) I need to seperate the upward stems from the downward stems. Is this right?
3) There is notation specifically written for only 1 piano (Harpsichord)..or 1 voice. Is this right?
4) Does the Piano play the upward or the downward stems?
