What clues are hiding in the forest … ?

Many years ago a very rare diamond disappeared on this sleepy island. Using the fun and interactive printable book alongside an accompanying set of online games, can you rule out the fakes and find the one true ‘lost diamond’?


Find the hidden clues in the music

  • The ‘Lost Diamond’ includes a printable sheet music book (with clues to find inside!) to keep forever so you can play your favourite tunes from the mystery as many times as you like! Get that tent set up in front of a roaring fire in ‘Going Camping Boogie’ and experience the magic of the mystical ‘Wishing Tree’.
  • There are six pieces to learn and the book comes in a PDF format for easy printing after checkout.
  • The pack also includes a ‘Diamond Case Files’ sheet so you can keep track of the investigation.
  • It is available in a choice of two levels for piano (beginner or early elementary) and also for treble instruments like the flute, clarinet, or saxophone (with optional duet part). The Music Teacher Guide gives more information.

Explore the island as you investigate

  • Paradise Island is split into three online interactive games with clues to unlock. Login from a computer, laptop, tablet or even your smartphone.
  • Find out more about the diamond and the people searching for it as you hike through the forest or enter the Bluestone Caves. Gather evidence as you explore an abandoned pirate ship or come across an old cabin at the top of a mountain. You will have access to Paradise Island for three months from the date of purchase (plenty of time to solve the mystery).
  • Successful detectives automatically unlock a printable certificate for identifying the real ‘lost diamond’!

Learning has never been so much fun

Clues can often only be unlocked by understanding music theory and searching the music for help.

  • Stumbling upon a small cave you discover a small box that has been dug out of the ground with the nearby shovel. Only unlock the box if you can answer the music theory question.
  • The ship in a bottle has been swirling around in the water for some time. Understanding the musical sign in the sheet music will reveal the message inside.
  • It even includes a little introduction to score analysis for beginners – search for patterns in the music to unlock evidence!

All six pieces have been composed by teacher of 20+ years, Susan Leigh.

  • Sleepy Snake Charming
  • Going Camping Boogie
  • The Wishing Tree
  • Rockin’ Around The Bat Cave
  • Pirate Dan and his Treasure Quest
  • Adventures of a Ship in a Bottle

An important note before purchase

Both parts of the interactive music book and online game for ‘The Lost Diamond’ are licensed for one student and only one printout of each book is allowed per purchase. Access to the online game is for four months from date of purchase for a single user. Each user gets one chance to guess the ‘lost diamond’. This also applies to music teachers purchasing the resource for their own students (please visit the Teacher Dashboard to buy the resource for your students). You do not have permission to use this single resource with multiple students and each student should have their own copy. Thank you for your understanding.
