I currently play the four common saxes, SATB, in slightly differing amounts but pretty much equally. I practice mostly on alto and tenor. I've discovered I have no real preference for any one voice but rather just have varying levels of familiarity with the instruments. For example, only playing soprano for about 4 months, it's the one I'm least familiar with. And having played alto for 4 years, and practicing it almost exclusively, I am most familiar with it. However if I practiced all of the horns equally I doubt I would have any one preference... just as long as my setup achieves a desirable tone, I am fine. However if I have like a bad reed or something, I might be prompted to switch reeds or horns in my practicing.
On a side note, I also don't seem to have any preference for classical or jazz. Lately I've been playing both nearly equally and am starting to develop a fondness for classical that I never had before through listening to a lot of it. I still listen to a lot of jazz.
I think I'm become the all-around saxman. This is good Anyone else have a similar experience or do you think you have a preference for certain horn(s) and style(s)?
