A first introduction to a cappella singing containing a choice repertoire of twenty choruses with pedagogical suggestions for interpretation. The choruses in this collection appear in the progressive order of their respective degrees of difficulty: First, two-part music, with occasional four-part endings; then, the use of the melodic style and imitation afforded by rounds and canons; and finally, choice material in four-part harmony. In these, special attention has been given to the melodic line of the harmony parts; awkward skips have been avoided, while both smooth melodic line and variety have been sought within the easy compass of youthful voices. Piano, or preferably reed organ if available, may be used freely while teaching the parts, but should be omitted as soon as the parts have been learned, and should, however, be used occasionally during rehearsal in order to test for accuracy in pitch.
