What is the best way to teach the sirens to them. I tried to demonstrate a siren, but the students keep playing a straight buzz with no changes in pitch. I try to tell them fast air for higher notes, and slower air for lower notes. Is there maybe another trick you have that works?
I have all of my beginners work mouthpiece sirens a BUNCH in the early stages. If I have a kid who can't hit one of the notes on their horn, I have them take their mp off, do a couple sirens to get a feel for the change in the lips, then put the instrument back together. Most times, it works and they get the picture; in a select few cases, not so much. Hope this helps, and good luck!
