Yesterday,during sectionals with Mr Lun,he told me about Warm Down.

Mr Lun said we must warm down because the next time we play,our embouchure will change.We might not notice it,but after a long time,our embouchure will be loosen and weak.
Also,this will happen especially when after we play alot of songs with fast,jumpy rhythm and long and high notes.

To warm down,we must buzz long and smoothly from LOW C to HIGH G,then from LOW C to HIGH C,then LOW C to MIDDLE G,after that LOW C to LOW E and then LONG of LOW C.
Must do this cycle a few times.

Mr Lun says that after you warm down,you can start playing back the trumpet like normal after between 20-40 mins break.

I think after every practice,we should warm down together.

Also,he told me for my personal playing is that I change my embouchure when I start playing high D and above.He told me should not do that because in the long run,I will suffer.
Maybe applies to all of us.
Then he said dont try to change now as we are having a concert very soon.So maybe after that I will change.

Ok,till next time.BB.
