I'm not a trained singer. I'm a rusty alto and I'm a bassoonist and pianist. However I want to improve my sight singing.

I'm looking for repertoire on which to practice. So far I've been using my folk song books but I think I need to stretch myself a bit further. More modulations, etc would be good.

One of my motivations is that I'm learning the tenor clef. My bassoon teacher says I'll learn it far faster if I try singing melodies in tenor clef. I'm quite happy to transcribe from treble to tenor. I have Sibelius but I do need melodies that will challenge me. Any suggestions would be welcome.

My singers use Schubertline for sight singing practice. Just choose a song, sing it through and then listen to the funny electronic version to see how accurate your reading was. I am not sure if you can transpose them into the tenor clef though.

Schubertline is great, as Petrat says.

Alternatively, don't rule out some Kodaly lessons - VERY useful indeed!
