Carlos plays electric guitar, and has a band named after him (His last name). The song that they performed 2nd in their set at Woodstock went on to peak at #9 on the Billboard charts on March 21, 1970. What is the name of the band and the song?

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"
