I keep emailing my friend its been 3 months and no respond she has been active but is not responding to meis there something wrong with me? We used to talk everydaybut now nothing
What happened?

It depends on what type of third separates the three notes.for example: if you have two mayor thirds is an "aumented chord"if you have two minor thirds is an "diminued chord"if you have one mayor first and then one minor is a "mayor chord"and inverted is a "minor chord"
