What is the difference between a tenor saxophone and a alto saxophone?

Tenor saxophone is a Bb instrument; that is, any written C for that instrument will be played as a Bb. Alto saxophone is an Eb instrument; similarly, any written C will be played as an Eb. Alto saxophone has a higher range and a sweeter, more melodic tone. Tenor saxophone has a rougher edge to the sound and has a lower range, though the ranges of both instruments can be extended through the use of altissimo. You can choose to play either instrument, as the fingerings of saxophones are designed to allow the player to switch instruments easily. If you learn either of the two instruments you should be able to learn to play the other (and even baritone and soprano saxophone) with relative ease.

A tenor saxophone is larger and plays lower tones. An alto sax is smaller and plays a little higher tones. The tenor usually plays more accompaniment while the alto usually has the melody or a counter melody. They have the same fingerings but don't have the same pitches. I play the tenor :)

Alto saxophone is higher, smaller, and has the melody more often. They also have slightly different fingerings. I guess which one you choose would depend mostly on whether you like to lead or support and how big an instrument you are willing to carry around.
