The Third recording below is of ME playing your solo on Euphonium at a tempo marking of 72. It's not perfect, but it's better than nothin', right? At the end the music calls for a ritardando that I did not do since I was trying to keep the beat with the metronome. But in the last line I did play the fermata and the "ten." (which means to hold that note longer). In these spots it sounds as though I was off the beat...so ignore the tick.
