I did my grade 5 singing exam a couple of days ago and it was my 10th practical exam in total!
Singing exams are just the same layout as other practical subjects, if you have taken others before.
Walk in, say 'hello', hand examiner list of pieces.
Wait for the ok to begin, then nod at your accompanist to start playing.
Sing song beautifully - lots of emotion - try and make examiner cry if its sad song and laugh if it's happy.
Finish, wait for ok to start next song.... etc. etc.
After you have sung your 3 songs, accompanist leaves and you r on your own!!! (Btw you can sing your 3 songs in any order), you sing your unaccompanied tradtional song. I did 'Drink to me only with thine eyes'. You play your own starting note on the piano and then sing it a cappella. Then you have your sight reading and aural tests for the grade.
It's not that scary really!!!
