That is, until they receive a mysterious message from the Scherzo Sisters: "PianoWorld needs help today, Silent Pianos get thrown away, To save the piano complete our tasks, That's all the Scherzo Sisters ask." Join Ned , Grumper and their friends on a mission to save the piano... Joanna MacGregor's PianoWorld is a unique way to motivate young pupils; they won't know they're working hard and you will certainly never hear them complaining about piano practice again! PianoWorld is a series of story-based tutors that entice pupils into a world of piano exploration. There are colourful characters whose escapades provide the inspiration for new techniques and pieces with illustrations by the highly-acclaimed 'Stik', that will have children and adults chuckling with delight. Games and puzzles galore provide hours of fun at, and away from the piano, and are valuable built-in revision. Each of the books in the series include catchy pieces in a range of styles, 'digital dodgems' and 'finger crunchers' provide focused study while 'technix boxes' give new information such as notes, musical markings and time signatures. Each book contains a CD bursting with adventures, pieces, games and accompaniments.
