Gradations is music of variety, of change, of progression, of growing up, even. Mozart&rsquo,s first keyboard minuets are here, as is a pair of Marcello sonatas. A sonatina by Clementi sits alongside 'Kaleidoscope' by Benjamin Lees. Bartók and Bach knew all about children&rsquo,s keyboard development and are each represented by absolute gems. César Franck&rsquo,s Doll&rsquo,s Lament and Kabalevsky&rsquo,s My stubborn little brother represent more negative childhood emotions, but in the main this is music of happiness and fun. Piano Moods is an exciting new piano series from Boosey & Hawkes. Each volume is devoted to a particular mood. The pieces chosen draw on Boosey & Hawkes' extensive collection of wonderful music as well as lesser-known gems from the past - some of them from surprising sources - and newly composed works.
