Finding a good saxophone teacher can help you sound and play better as well as lowering the amount of time you spend practicing incorrectly or just inefficiently.
A good place to check for a teacher is the local music store. They often have more teachers for piano and guitar, but often will have a woodwinds teacher.
Go to the store to meet them. Ask about their background, style, cost, and other concerns you may have. Listen to their sound and think about whether you think they will help you get where you want to be on saxophone.
You can also check the yellow pages under “Music Instruction – Instrumental” and Craigs List and/or classified ads for work wanted in the newspaper.
Universities and colleges also often have music teachers you can take private lessons from, but look into the application process since they usually have rules about enrollment.
