Customer Reviews

CHORDiCA XL is not based on conventional theory

For those of you that think the 'm' means 'minor', you are mistaken. CHORDiCA is based on Scoreless Music. It's not even based on the Nashville Number System.

'm' means 'mode change. All numbers representing harmonics have a default 'mode'. 1, 4, and 5 ALWAYS form a major triad. 2, 3 and 6 ALWAYS form a minor triad. 1m is when it is 'mode changed', thus making a minor triad. 2m will do the opposite, since 2 is always minor. 2m will therefore form a major triad.

@ Netnut2003. The chords are not marked major and minor. The app doesn't need tweaking as it works perfectly. What needs to be understood is the Scoreless Music Method on which the CHORDiCA XL is built on.

I love this thing!

I write songs and I love this APP because it sounds like songs from the '60s no matter how you tap it. Cool!


Definitely a cool app for hearing harmonies. Never learned the scoreless music method but not hard to figure out. Cool
