This is a continuation of Level Up #1.
If your students can do Level Up #1 with no issues, and are ready for a higher difficulty of warm up, this is the next step up.
This warm up uses a wider range of notes - just over an octave.
It is helpful for woodwind students if you do Extenders #1 before you start Level Up #2 if your clarinet students can't go over the break.
If your students are ready for the next step, but Level Up #2 is a little too hard for them, consider continuing using Level Up #1, while adding in parts of Level Up #2 a little at a time.
