This progressive method, written by Ralph Allwood and Andrew Morris, provides a carefully paced approach to the sight reading requirements of Trinity Singing exams at Grade 6 to Grade 8, for high voice. 

For each grade there are ten lessons, each with a clear area of focus, featuring a wide range of classical genres. Stage-appropriate sight reading tips, both general and specific to the voice, are given along the way.

Official Trinity specimen sight singing tests conclude each grade section. By the time the student has completed the ten lessons they should be well prepared to cope with the demands of these tests.
