The Music Ruler comes with a fun instructional book using the twanging techniques of modern ruler maestro Dan Wieden, to get you creating musically masterpieces in no time! - Sliding the ruler up towards the edge of the desk alters the note, enabling you to play anything from Abba to Jay-Z!
Playing with your music ruler doesn't involve controlled breathing. Or co-ordination. Or timing of any kind. It doesn't even involve leaving your chair... Your new found musical expertise will impress others. You could lead your office in an impromptu, team-building sing-along. And then you could use your Music Ruler to underline your ever-growing To Do List!
