‘Interval Detective’ | Card Game AND Board Game!

Help your students MASTER intervals on keyboard, BOOST keyboard geography, and IMPROVE sight reading, with these TWO versatile and fun Detective Games.

Intervals are the basic building blocks of melody and harmony so recognising intervals visually – both on the staff and on the keyboard – is an important skill for students to master.  Fluency with music intervals helps budding musicians improve intervallic sight reading, understand keyboard geography, and boost music theory skills!

This game set gives gives you two fun games to help students understand, measure, write & read musical intervals.  Additionally, it also incorporates kinaesthetic, visual and auditory learning.  The Card Game Sets are ideal to use in one-on-one music lessons.  Students struggling with sight reading? You can use them as a lesson starter or as a change of activity half way through!  The Board Game Set extends the Card Games, giving lots of fun repetition for optimal learning.  Ideal for group class or ‘Piano Party’ events, and it can also be played with just student and teacher in lesson time.

The ‘COMPLETE Bundle’ includes:

  • All 3 levels of the original ‘Interval Clue Cards’:  Beginner, Elementary AND Intermediate levels.  That’s a total of 144 challenge cards, and since each card has 5 interval clues this gives you over 700 music interval quiz questions. Lay the foundation for sight reading and music theory!
  • The full size printable Game Board:  Make the game board large, medium, or small, you can set the size you want in your printer properties
  • Player Tokens and ‘Detective Kit’ Cards – Colourful and fun!  All ready to print and play.
  • Rules & set-up instructions for all the Card Games – Easy to play in one-on-one lesson times
  • Rules & set-up instructions for the Board Game:  Print and play rules so students can easily set it up themselves and play it as a group, therefore making it flexible to use in different learning environments.
  • A mini ‘white board’ for each of the 3 levels – These cute ‘whiteboards’ are ready to print and laminate. Useful with both the card games and board game, and a great way to reinforce sight reading skills.
  • ‘My Gaming Record’ chart for each student to track their own progress – a great way to set longer term goals for improvement.
  • Three colourful ‘official’ Certificates of Achievement’ – one for each level.  Challenge students to collect all three certificates!
  • Teacher ‘helper key’ page included with level 3, so it’s easy to check student’s answers 😉
  • Immediate availability by digital download from your customer dashboard.  All the prep work, layout, and graphic design is done so you can just print and play.  Print it yourself or take it to a print shop – Printing instructions are all included
  • Studio Licence – allows you to print these cards for all your own students, for at home practice, if needed.
The original CARD GAME SET itself has three levels:  The beginner level focuses on interval measuring skills up to a 5th; the elementary level adds in larger intervals, up to an octave; and the intermediate level helps students learn how to name intervals by quality as well as number!

Each Card Game Level includes:

  • 48 ‘Interval Clue Cards’ in each level
  • Each individual card has 5 interval clues for students to work out, to find the ‘missing note’.  This gives plenty of fresh challenges and lots of revision – with a multitude of interval questions!
  • Intervals included are both ascending and descending, reinforcing the concept of ‘high’ and ‘low’ notes, direction on the keyboard, and pitch contour in music. These basic skills are the building blocks of good keyboard geography and sight reading skills!
  • The artwork is bright, colourful and engaging – capturing students’ attention and making it feel like a ‘real’ game.
  • A mini ‘white board’ ready to print, laminate and use with the game.  Using the whiteboard helps students connect the ‘keyboard geography’ of physical intervals on the keyboard to written music notation.  A great tool to improve sight reading!
  • ‘My Gaming Record’ chart for each student to track their progress. Give every student their own chart to keep, or display them around the room.  Make it competitive or non-competitive, you choose!
  • A colourful ‘official’ certificate of achievement that you can award to students who complete the number of cards you set for them. Especially great to build confidence AND motivation.
  • The Studio Licence means you can also print ‘whiteboards’, record charts, and card sets to give all your own students – Great for online teaching too!
  • Everything is immediately available in your customer dashboard. This digital download is ready to print and play. And all the printing instructions and game rules are included!

  • This is such a good product!

    This is great for helping kids to learn intervals, and also where the note on the staff corresponds with the actual note on the Keyboard. It was really helpful with a particular student of mine, who was struggling with the 'which-note-up-there-is-which-note-down-here' syndrome!
