About EIS


INTRODUCTION TO:
Lyle Murphy’s music composition method,
“HORIZONTAL COMPOSITION, the EQUAL INTERVAL SYSTEM” or EIS.

This system is not related in anyway to any other systems involving
12 tones, especially ones by Schoenberg, Slonimsky or Schillinger.


 
This course includes: Harmony, Melodic Development, Composition, Arranging and Orchestration. It does not include style, as the techniques learned can be used in any context.
 
The Murphy system is a complete system that proposes new relationships and techniques unique to Horizontal Composition, while encompassing Diatonic, Classical, Contemporary or Pop sounds, and approaches them from an original point of view having nothing in common with other known methods.
 

Horizontal Composition

 

EIS is an original and unique music course that was created by Mr. Murphy, for students and professional musicians who wish to advance in Arranging/Composing/and Orchestration.

 
In other words, this system can be used to organize the sounds of any historical period of music while also providing a basis for finding new and unique sounds from the simplest to the farthest relationships possible with 12 equal intervals. All of it accomplished with only half a dozen rules.
 
Horizontal Composition refers to the creation of individual lines that hang together in a way that could only be seen through a vertical (harmonic) dimension previously. This allows for greater flexibility and melodic interest in each individual voice with no doubling of parts. 


Compose More Quickly

 
As the course proceeds you will gradually build your own musical reference library filled with your own musical ideas created in each lesson. You will be able to compose more quickly and originally when needed.
 
The course can be useful for instrumentalists as well.
 
The advanced theory includes Motion Picture and TV Scoring.
