In August of 2013 I completed Lyle “Spud” Murphy’s course, the System of Horizontal Composition based on Equal Intervals — or EIS (Equal Interval System). The course teaches composition and arranging in an unconventional way: the emphasis is on technique rather than style or history. Another unique aspect of the course is, that it is only being taught individually in a direct teacher/student relationship.
I cannot begin to describe what this system has done for me musically.

I love Spud Murphy big band arrangements from the 30's, big fan. I have some materials from that equal interval system in a storage box somewhere in my garage. I think Quincy Jones was a big follower of the Murphy system. Here is a good CD of Spud Murphy arrangements done by Mora's Modern Rhythmists. EQUAL INTERVAL SYSTEM® The Equal Interval System®, or EIS®, is an instructional course in music composition, arranging, and orchestration. The work is the expression of Lyle “Spud” Murphy’s® musical theory based on his observations of the harmonic series or “nature’s overtones” along.


- The Equal Interval System (EIS) (also known as the System of Horizontal Composition based on Equal Intervals) is a modern system of music composition developed by Murphy over a lifetime of research. Several courses based upon the EIS system we re taught at Pasadena City College. Many notable composers and arrangers have been students of the.
- Spud Murphy was an exceptionally versatile jazz and swing musician, who played several instruments. Which he called the Equal Interval System, and among the noted musicians who trained under.
- Describing Horizontal Composition, the Equal Interval System of Spud Murphy is a nearly impossible task. There are as many facets, embedded truths, brilliant theories, examples, and revelations about every known aspect of modern composition as one could only dream of.
Here are some examples of what I have written using my newly acquired skills.

Currently, there are only a few people in the world who are certified to teach EIS and who were tutored by Spud, who died in 2005. Until recently, if you wanted to take the course, you had to go to one of these senior teachers (although you still can of course!).
But now, three new teachers have been appointed and I am very happy and proud to announce that I am one of them (the other two being Matt Gibbs and Gary Atkins).
If you want to study EIS with me or with somebody else, contact Spud’s daughter Lilith through the EIS website (link below).
