This stage of the song learning is critical: many actors have difficulty with singing because they cannot get used to having both the rhythm and the pace of the text dictated by the music. Think of the musical structure as an extra dimension that you can use in performance, rather than as a straightjacket. Do not move on to the next stage until you are confident that you have mastered the note rhythms. 3. Siren the melody line by line. Sirening programmes in the notes of the song, helping you embed muscle memory for pitch. If you do not read music and have no instrument to give you the actual pitch, work with someone who can play the melody for you to listen to and who can play along with you when you repeat it.
