I am taking my courage in both hands and am auditioning for a choir in Cardiff on Monday. I have been singing for years, but have usually managed to get away without auditioning, so I am very apprehensive about it. I have looked at loads of music and can find very little that I like to have as an audition piece. Most of the pieces I know are choral and therefore singing just the soprano line without the other parts sounds very thin and bodiless, plus without the other parts I keep going flat for some reason. Other folk songs and things don't have enough range for an audition piece, they aren't interesting enough and only span about half and octave so they are no use.
Plus I hate listening to myself singing alone - I am very much a choral singer. I don't mind being heard when singing with other people, I can sing my part alone if the rest of the choir is singing, but by myself I get self conscious and don't sing so well.
However the worst that can happen is that I don't get in.
