re: Questions for the band geeks

1 - The transition from Alto to Tenor Sax is relatively easy if you can handle the weight and airflow requirements for the larger tenor... you don't just need bigger stature, you need bigger lungs.

2 - That said, both are good choices because both are used frequently in Jazz and Rock and Pop music as well as HS/College bands. If you get good at either, you can gig with bands on the side.

Unless you're going into Jazz or professional orchestras later on, something like a Trumpet or Trombone isn't going to do you much good in club and bar bands (unless you're in, say, a Chicago cover band). Both kinds of sax you mention are frequently used in all manner of music.
