Eb Major
The simplest way is to transpose everything down a third (three semi-tones) Also, the piano is tuned in concert and the alto saxophone, as you know, is in Eb.
The word "transpose" is term used in music. An example of a sentence using the word would be: We will have to transpose this piece down a major fourth to the key of C.
I'm pretty sure baritone horn and piano are both concert pitched instruments. The Baritone Sax is a transposing instrument and is pitched in Eb. This means that if you play a C it will sound as Eb. Therefore you need to transpose the piano part down 3 semitones. for example... you see a written Eb and you play 3 semitones lower... C You see a written C and you play an A. If in doubt... simply go to a piano and play a C then find the note on your sax.
