i found that bari alto are Eb and soprano and tenor are Bb

i know how to transpose musics into Eb like say from um a violin piece but i have no clue to transposing Bb my sister plays Bb clarinet so i was wondering if any of the people hanging around in this website knows it...

A C on a Bb instrument is a Bb on a concert instrument (piano, guitar, flute) You can print out a transpostition chart which will tell you everything you need to know at http://www.saxontheweb.net/Transposition.html Just copy and paste that to your browser.
