Teach music theory and composition with musical dice! This 7 sided dice has the notes out of a scale on it. All songs are made up of notes in a scale – the scale, and chords that go with it, turn random notes generated by the music maker dice into amazing themes and songs.

In order to compose a song:

  1. Choose a musical scale or key signature for your song, and then create the music maker dice that has the key signature that you need.
  2. Start your song on a dominate note in your key signature.
  3. Roll your musical dice, and use the notes that come up to create a melody. So long as all of your notes come out of the same key signature it will sound great!
  4. Choose your favorite note sequence for your repeating theme.
  5. Most songs end where they begin – pull that melody back to the first note you started on!

In order to teach music theory:

Roll the music maker dice, and then find the note on a clef.
Roll the music maker dice, and play the note that comes up on your instrument.
Roll the dice, and play a chord to go with that note! Can you play the minor, major, 6th, 7th etc. chords?

See example you tubes where we made music with random notes:

When printing, lay it flat, and no print support structure will be needed. If you scale the size down too much it might be a little hard to read the text – a larger sized dice will probably work the best. The letters will show up better in lighter colored filaments.


How I Designed This

Inventor Tutorial!

The music maker dice was created using AutoDesk’s Inventor Software, and then exported to an STL file.

Free Inventor software for students and educators:

The Music maker was created by extruding 7 sided polygons. Because of the odd number of sides that is needed in this dice, a central polygon was created so that when the dice lands only one musical note is sitting on top. Letters were added with the text tool, and extruded into the axial dice faces. The key signatures that match the notes are inscribed in the ends of the dice. Each set of notes can be matched to two different scales – a minor and a major.

Create first polygon, and dimension to desired size.

Extrude first polygon

Create an inner rotated polygon:

Extrude Inner polygon

Create the top polygon:

Extrude all polygons to the same height:

Write centered bold large text on each side corresponding to the notes in your scale:

Rotate your text, then copy and paste it onto all of the other sides. Double click on each of the sides to change the letters to what you would like them to be, then cut the letters and designs into your piece.

What does lay it flat mean? It seems to have the origin set on an angled edge, am I supposed to rotate it so it lies flat along one edge of the hegaxonal edge, or flip it sidewise so the sits flat on one of the circles? Thanks
[Update] So I put it on a flat of the 7 sided piece and it worked out out, The last one I added some supports and that helped it stick to the bed a bit better, one of my middle attempts printed 3/4"s through and then apparently came off the bed! There is very little surface area on the bed w/o supports, so the supports more helped with surface area to the bed, then because they are needed to successfully build.

Sorry for the late reply! Thinking about it some more, it might print better by rotating it 90° up onto its end - fillet the inside edge so the small overhang would not need a support? I'll create a remix when I get a chance to see if it would help.

I wouldn't worry about it, the one thing I had a problem with that seemed to help the most was actually getting the model "flat" on the flats, by default it landed in my slicer on an edge, I selected a flat, but that apparently got it cocked slightly wrong. Once I got both edges flat on the bottom it seemed to go better for my 3rd print.
