The 1, 5, 6, 4, Common Interval Pattern is an interesting one. In the key of C the chord one would play would be a C maj, G maj, A min, and a F maj respectively. Unlike the 1, 5, 6, the 4 at the end adds a little different of a feel like there is an extra line to get some information in and make it feel more emphasized. I utilize the 1, 5, 6, 4 in a song for the chorus I have been working on called “Don’t Tread on Me.” The 4 allows for an interesting line of response to the underling ideas discussed in the verse and adds a layer of complexity. The 1, 5, 6, 4 interval pattern has been used in many popular songs beyond just one that I might compose, overall it provides an interesting feel for the listener to appreciate.
