There are currently eight volumes in the Eye Tunes series for piano: starting at grade 1 and culminating in a duets album, grades 6-8. Additionally, there …are three volumes pitched at the “Easy” level: Eye Tunes for Rocket Scientists, Eye Tunes for Zoo Keepers and Eye Tunes: Liquorice Allsorts. These are not tutor books for the raw beginner, but resources aimed at expanding and stimulating players who have already had the benefit of a little grounding (typically anywhere from a matter of weeks to a year or more, depending on age and aptitude). Hence the overall scope of these books lies somewhere between what might be thought of as between “preparatory, “initial” and “early grades”.
