Book 6 of In Recital? with Christmas Favorites reinforces concepts such as rhythmic patterns of dotted eighth notes, triplets, and sixteenth notes; pieces in simple, compound, and mixed meters; plus ornamentation consisting of grace notes and trills. Technical challenges encompass one- and two-octave scales, octaves, rolled chords, and hand-over-hand configurations. A delightful inclusion in this volume are three well-known Spanish carols. Early intermediate arrangements by Bober, Brown, Costley, McLean, Olson, and Schultz.
