I recommend you ignore all of that.Stamped Records wrote: ↑Thu Oct 11, 2018 2:25 pm The presence of the minor 3rd did confuse me for the Esus4 example I have to say.
Sus4 as you apparently realize is a replacement for the third. It comes from a literal suspension in CPP use, a tone from the previous harmony held over, here resulting in a suspended 4th. It may be resolved during the harmony it's suspended over.
If there is a chord with both the 3rd and 4th it tends to be called an 11th chord. Minor chord with a P4? 11th chord, full stop. Typical is m7 construction add the 4 or 11. Could call it add4 .
In no sense is there a minor/#5. E G C already has a useful name/identity.
