I'm not familiar with a "tritone"

I see it a lot like this:

B----15----
G----14----


And the in OP in Back in Black.. I don't undderstand.. Can you explain more?

they're both just intervals, the first one is a major third interval, second is a tritone / diminshed 5th / sharp 4

edit: I take that back, the second one is a perfect 4th

the first one is either a major fifth or a fourth depending on what note you play first ( a- e being the fifth, e- a being the fourth), the second one is a third ( d - f sharp) or sixth (f sharp- d)

if your playing them as substitutions for chords, the first could be played for either an A, A minor, or A9. the second is pretty much just a D, minus the fifth.

Is this just an interval as well then?


an interval is basically the distance between two notes. when you play them together in a diad, you normally refer to it as whatever the interval between them is.

like they said,a note to another note is an interval of something.

what you listed is called a dyad.

a stack of 3 notes make a triad (chord).the notes will be a certain distance from one
note to the next. a C chord has the notes C E G

the distance from C to E is interval of Maj 3rd
the distance from E to G is an interval of a Min 3rd
the distance from C to G is an interval of a perfect 5th

the C to G would also be a dyad also known as a power chord.a website on basic music theory will tell you how this is done.
