If you are a musician playing an instrument different from piano, please try to learn to perform it as your second instrument in a very short time.

In pianoatsight.com you will find a practical method for learning it.

There you will find also advanced lessons about jazz piano, modern harmony, jazz chords, salsa, bossa and latin rhythms.

There are also free sheet music of classical and latin pieces, and some anthems and hymns in transcriptions and arrangements by Alberto Betancourt.
