## What's the difference between a minor interval and a diminished interval (music theor

Hi,

I'm trying to get through my music theory homework and I'm having some difficulty distinguishing between a minor interval and a diminished interval...

We only have two notes per chord (someone suggested looking at the third note... of which there are NONE) and they DO use flats and sharps.

So, 10 points to whomever can explain how to find a minor interval, a diminished interval, and how to tell the difference between the two in the simplest way.

I'm not 100% sure what you're asking. Wouldn't a minor interval simply be a 1 to 3b? So given that we have the Cmaj scale; wouldn't the notes of the chord be C - Eb/D#? And for Dim, the first 2 intervals are the same, 1-3b again? I know all the intervals for each type of chord, but it's a bit hard when there's only 2 notes... So um, what if we use the third diminished interval, a flat fifth? So it would be C - Gb/F#? I'm a bit unsure when it comes to intervals.

EDIT: For the diminished one, what about 3b - 5b? Eb - Gb? Fuck, I dunno.

I'm interested to see if anyone else can answer this...

I know this is way past, but oh well. First of all intervals are classified by Majors, Minors, Augmented and Diminshed. So, by starting from your base note, you have this following table when you are in a major scale.

1U 2M 3M 4P 5P 6M 7M 8P (Key: U (Unison, same note) M (Major) P(Perfect))

From here, you can "play" with the intervals for example if you have a C followed by a D, that would be a 2M, but, if you had a C followed by Db, that would be a 2m (minor). And if you had a C followed by a Dbb that'd be 2dim.

Remember that intervals just classify the notes, and gives them a name, of course you know that Dbb is actually C, but, when you are in a scale you avoid repeating the same letter. If I could see your homework, it would be much easier to explain, but, you most likely already gave it in.

Maybe, but it doesn't hurt anyone if I respond though.
