Damn, it's hard to explain this in English! Anyways, I'll give it a try...
So dim is from diminuated and aug is from augmented (do these words even exist?). So a dim chord has just small terces and an aug chord has just big terces.:laugh3: Does anyone understand what I want to say here?
So let me give you an example: the C aug chord is made from the C, E and G# notes (you can add another C too, at the end) and the C dim chord is C, Eb, Gb and A (can add the high C here too). The dim chord goes up with a half note to a minor chord (what?:) ). So after a C dim chord put a C# minor chord and so on. It will sound good.
Now the G# dim is G#, B, D and F. The F#7 aug is F#, A# and D. I dont't know what they want with that 7. Can try and F or an E. Depends on how the original sounds. Thats about it. Hope you understood something.
