Hi all. First post and as green as you can get. I found an old (late 1920's) alto with a curved neck and states it's "low pitch" Here's where I show my "greeness." Do they or did they ever make altos with a curved neck or is the owner wrong? Also, not sure what "low pitch" means. Is the sax in a different key other than Bb or does it have to do with A-240 which I know nothing about either. I tried to tell you I was green, but you wouldn't listen. Thanks for giving me my first sax lesson.
