The Melody Master is a fantastic cartridge that, when used with the Vectrex light pen, introduces you to the exciting world of music. It lets you create your own melodies and even has the ability to play flute and piano harmonies with snare and cymbal rhythm sections. You can create your own electronic musical masterpiece and amaze your friends that this interactive cartridge in a game system of a quarter of a century has allowed you to create it. There is also a curriculum for those of us who are not musically inclined. "Songman" will teach you to recognize notes and define other concepts of musical notation. This is a true interactive educational and creative experience. In my opinion, the feel of this cartridge is rated 9-10, control 7-10 and overall 8-10. It's a funny name for software
