Chord Fusion

Chord Fusion

Chord Fusion a game where you combine notes to make chords and solve puzzles.

Drag and drop notes together to make chords.  

Drag chords into the dark semicircle at the top to split them back out into their component parts.

Each level has one or more objectives squares, you can hover over them to see what chords are required (see below for more help) and they will light up if you make a chord that matches the objective.

The code is available at https://github.com/wainwrightmark/chord-fusion

If you are not well versed in music theory this game might be quite difficult. Here are some tips:

If you hover over the objective, it will tell you the required chord and the required intervals.  For example a major chord is 0 4 7. This means that you need three notes such that the first note is 4 semitones lower than the second and 7 semitones lower than the third.

For example C is 4 semitones lower than E and 7 semitones lower than G so CEG is a major chord.

The table below shows the intervals relative to a C note.

Note	Interval
C	0
Db	1
D	2
Eb	3
E	4
F	5
Gb	6
G	7
Ab	8
A	9
Bb	10
B	11

To calculate the notes for another chord, add the index of the root to the intervals and then subtract 12 from numbers greater than 12.

For example, for an Ab minor, the raw intervals are 0, 3, 7 so you add 8 to each to get 8, 11, 15 which then becomes, 8, 11, 3. Looking those notes up in the table, you get Ab, B, Eb.

Good luck!
