Eliza:
Warmup exercise: play the following pattern on a note of your choice (ie second line G), tap your foot throughout if that helps: whole note (4 beats) half rest (2 beats) whole note.
Continue work on Accidentally in Love from Shrek, make sure to use the proper fingerings (also in generally you should be using pencil to make markings like fingering, so you can correct any errors)
Continue to explore the different sounds on the horn by just noodling about your range, use steady air and when playing higher, aim air stream downward, and when moving lower pivot the airstream upward.
Work specifically on playing the C major chord: middle C, first line E, second line G. move between all three notes, then see if you can go smoothly from c to g.
Happy Practicing!
