The Flex-Ability series, arranged by Victor Lopez, fills the need for multi-level instrumentalists to play popular music together. Each instrument book includes 11 songs in four-part score form. The top line (solo) is for level 2 1/2-3. The second line (duet/harmony) is for level 2-2 1/2. The thirdline (trio/harmony) is for level 1 1/2. The bottom line (harmony or bass line) is for level 1/2-1(only whole, half, dotted half, and quarter notes and rests). The arrangements are carefully crafted to be educationally sound. Optional octaves and cue notes are included to allow for range flexibility. The songs are: Jingle Bells * Santa Claus Is CominŽ to Town * Have Yourself a Merry Little Christmas * (IŽm GettinŽ) NuttinŽ for Christmas * Frosty the Snowman * IŽll Be Home for Christmas * Angels We Have Heard on High * Joy to the World * We Wish You a Merry Christmas * Auld Lang Syne * ChanukahMedley: Chanukah/I Have a Little Dreydl.
