Could someone offer advice on what would be the best lyre and strap for a left-handed Wagner tuba please? I have tried a euphonium strap and have a removable holder for a lyre but the instrument was unstable when I was playing and the music wobbled too much for me to be able to read it. I am very new to brass but experienced on woodwind and was amazed at how difficult it was. I sounded dreadful! Your advice would be much appreciated.
