I'm a novice harpsichordist, and the first music that I've decided to learn is the continuo part of Vivaldi's Summer III presto. However, there's a problem. The sheet music I got doesn't sound like the recording I have. Because of this, I've listened to a bunch of recordings, and the harpsichord plays differently in them. In the notes I have, during the opening the harpsichord plays the same 16th note based melody as the strings. In the recording that I have, it plays some stacchato thing, and in another recording I heard on Youtube, it just taps a chord for like one eight note per measure. Did the composer release different versions? Is there a legitimate one that's the proper way to play it? Am I supposed to make up my own part within the harmony?
Please help. Thanks!
I didn't find the right solution from the Internet.
