Founded on the premise that young singers tend to view each key as a separate "language," this creative approach to sight singing addresses the needs of visual learners by organizing the treble and bass clef exercises key by key.  Volume 1 provides visual orientation and melodies to sight read in seven keys.  Each section begins with the scale and outlines the tonic chord for that key, followed by a tonal drill.  Students are introduced to the intervals of seconds, thirds, fourths, fifths and sixths. Volume 2 is designed to hone the reading skills of advanced choirs and to provide preparatory materials for the rehearsal and performance of works in minor tonalities, while Volume 3 focuses on modulating tonalities.
