Identify the first note of the song. If you can't read music, ask someone to help you determine the first note.
Locate the same note on the pitch pipe.
Blow into the hole marked as the same note as the first note of your song. Don't blow as hard as you can, as this can distort the pitch. Use a gentle, steady breath as you blow.
Listen carefully to the pitch as you blow it.
Match the pitch with your voice as you begin singing the song.
