1. Air leaks. Air leaks can occur in a variety of places on an alto saxophone, but some common spots include the neck, the body, and the keywork. Air leaks can cause a variety of problems, including:
* Loss of air pressure
* Difficulty playing high notes
* Squeaking or buzzing sounds
* A breathy or raspy tone
To identify an air leak, hold your saxophone in playing position and blow air into the mouthpiece. If you hear any hissing or whistling sounds, you may have an air leak. You can also check for air leaks by looking for any places where the felt or cork is damaged or missing.
2. Reed problems. The reed is a thin piece of wood that vibrates when air passes over it, creating the sound of the saxophone. Common reed problems include:
* Chipped or broken reed
* Reed too thick or too thin
* Reed too hard or too soft
* Reed not seated properly
Reed problems can cause a variety of problems, including:
* Difficulty playing in tune
* Squeaking or buzzing sounds

To identify a reed problem, visually inspect the reed for damage. If the reed is chipped or broken, it will need to be replaced. You can also try playing with different reeds to see if that makes a difference.
3. Keywork problems. The keywork is the mechanism that opens and closes the holes in the saxophone body. Common keywork problems include:
* Bent or misaligned keys
* Loose or missing screws

Keywork problems can cause a variety of problems, including:
* Difficulty playing certain notes

To identify a keywork problem, visually inspect the keywork for any damage. If you see any bent or misaligned keys, you may need to have them adjusted or repaired. You can also try tightening any loose screws and cleaning any sticky or sluggish keys.
4. Embouchure problems. The embouchure is the way you position your mouth on the saxophone mouthpiece. Common embouchure problems include:
