music educational books for piano

This is what Purrfect Practice was looking for in their logo design

I need a logo deign for a new company called Purrfect Practice that writes and publishes educational music books for beginner to advanced students.

My initial product is a series of books titled Purrfect Scales Grades 1, 2, etc.

1) the logo should work in single color (b/w),
2) Playful but not overly childish,or cartoony
3) silhouette of a cat is acceptable with slight feminine appeal
4) Vertical positioning of graphic and text is preferred over horizontal layout,
5) logo illustration/graphic can have the “inked” effect

This project has been re-opened due to licensing issues with my original choice. Read more
