Chord List

There is less than universal consensus about chord names and symbols and this has given rise to a number of possible ways of writing the same chord. Here is a list of the most commonly found chords that includes commonly used alternative names and symbols.

This is not a complete list but I believe it covers all chords whose names or symbols might potentially confuse people!

For example: C Seventh sharp five flat nine = C7#5b9
