Note from Matt Godwin:

Hey Kenneth, FlashChord is exactly what I was looking for. Unfortunately, when "any (random key)" is selected with just Major and Minor chords checked, it only picks minor chords. I started to try and write my own version in C# but writing an accurate metronome is not as easy as it sounds, lol. If you get around to fixing this bug, please let me know. Anyway, thanks for making this. Take care, Matt

I've been able to reproduce this with other qualities checked, like 7, m7 and any key.

See #86 for duplicate bug.

Acceptance Criteria

• Chord quality should be as random as intended

Approach

• Debug to determine what is happening and resolve
• Noting that I plan to use Chrome's JS debugging for the first time as explained here: https://developer.chrome.com/docs/devtools/javascript/
