These two new releases, the GREEN LARGE PRINT SONG BOOK MUSIC EDITION SECOND EDITION and GREEN LARGE PRINT SONG BOOK MUSIC EDITION LOWER KEY SUPPLEMENT have been designed as the perfect combination to support singing groups and choirs. Where we considered the key the song was originally written in may be a little too high for seniors who want to enjoy choral and group singing, we have transposed those songs to a lower key in the LOWER KEY SUPPLEMENT. There are 44 songs out of the 200 in the Green Book Collection included in the supplement. Here you can purchase both the GREEN LARGE PRINT SONG BOOK MUSIC EDITION SECOND EDITION and the LOWER KEY SUPPLEMENT together as a cost-effective package.
