| It could mean:
1. that you are playing flat, in terms of pitch (intonation), and/or
2. you are playing low, in terms of the slots of your instrument. If you think of the notes in your horn as a target, you aren't playing in the "bull's eye." (center)
The reasons could be:
1. there is a certain sound color (texture) from playing low
2. embouchure training/strength
3. air support
Hope this helps,
