On the trombone, false tones are most common in the low register. This is because the low notes require a more relaxed embouchure, which makes it more difficult to control the pitch. However, false tones can occur in any register if the player is not careful.
There are three main types of false tones on the trombone:
- Lip slurs: These false tones occur when the player slides the mouthpiece up or down on the lips, causing the pitch to change.
- Tongue slurs: These false tones occur when the player uses the tongue to articulate a note, causing the pitch to change.
- Embouchure changes: These false tones occur when the player changes the shape of the lips, causing the pitch to change.
False tones can be difficult to avoid, but there are a few things the player can do to minimize the risk of producing them. These include:
- Practicing with a tuner to make sure that the pitch is correct.
- Using a relaxed embouchure, especially in the low register.
- Articulating notes clearly and smoothly.
- Avoiding any sudden changes in embouchure.
