I just want to confirm some things I think I know about diminished chords.
This week my guitar teacher told me that the form of a diminished chord is 1-b3-b5. However, on a sheet given to me a while back by a different guitar teacher it says the form is 1-b3-5-b7. I think the first one is right and the second one is actually a m7 form, not diminished at all (a typo on the sheet). Am I right?
Assuming 1-b3-b5 is the right answer, it seems to me that since the 3 is flat, this is a minor form to start with, so would it be accurate to say that this can be called a minor dimininshed form also (mdim)?
When I asked my guitar teacher the second question above, he said YES. Further, he said there is a form which looks like: 1-3-b5. He called this "half diminished". I had never heard of that before. Have you?
To me, a sensible convention would be to say the following:
- 1-3-b5 = diminished
- 1-b3-b5 = minor diminished
Is that legitimate?
Anyway, I'm a bit confused. please help.
