I've been searching the web every since I have seen the YouTube Video Tuba and Euphonium the Individual and the Ensemble which I honestly wish I found sooner than later because it gave me some great insight on how my instrument works the types and the general good ways of practicing my instrument. Towards the end they play a Quartet called When I'm 64 by tuck woo. I don't know currently whether it was even something on the internet to begin with, whether it's something I just don't have access to or whether it's just somewhere I am not looking hard enough. I tried to contact one of the Euphoniums from the video but it seems like he doesn't wan't to talk to me about for some reason. So my last resort source of where I can find it would be here. I have found the Quartet from the video that plays at the end. Stars and Stripes forever arranged by david werden. I'm really interested in this one quartet part. If I am going to even make way on it I need to get it as soon as I can because my schools Recital is coming up (like in 2 1/2 months, but we could only meet once maybe twice a week).
