Online Paid Courses
I have written most of my works in Sibelius, although I also use other music notation programs. With the knowledge accumulated over sixteen years of using Sibelius, I have designed two online self-instructional courses to teach new users how to master the program in no time. The courses are being sold at Udemy.com at a very affordable price but, for the moment, both are offered only in Spanish. However, it's possible that in the future I might find the time to make English versions and even create one or two additional courses to cover more advanced features of the program.
Aspects of Musical Composition
Here's a video I made some time ago about applying concepts of set theory to music composition. Set Theory is a tool for analysis developed mainly by Allen Forte in his book "The Structure of Atonal Music". This video explains the basic concepts behind this tool and briefly explains how I used it to write my piece "Il giardino della casa", for flute and guitar.
