This course is divided by the following steps:


Variations on a theme

In this wonderful first section of the course, Mattia teaches you how to transform a simple theme into a longer piece using interesting variations.

In this section you will slowly be introduced to various development techniques like diatonic variations, variations using modes, non-diatonic variations, modulations and more.

By the end of this section you will be able to expand your musical ideas and themes, into longer, more complex compositions that keep the listeners fascinated. This section will lay the necessary fundamentals to advanced orchestral music in the style of classic hollywood composers.

In the second section of the course, Mattia starts by explaining how to come up with a proper piano sketch that translates well to the orchestra.

What students have to say


"The truth is that I am delighted with this course because Mattia has a great ability to explain and turn a simple melody into a harmony of great interest. Especially with this course, I am learning how to structure my musical sketches effectively and how to compose more efficiently. Without a doubt, I strongly recommend this course primarily to those people who need to continue improving their level of creating orchestral mockups with interesting harmonies."

Ángel Cortiñas



20th Century Orchestral Writing was a real game changer for me. Since I have no formal training, I wasn't aware how important it is to first clarify your musical ideas and tie them together harmonically before attempting orchestration. Mattia's clear explanations about the importance of piano sketching and excellent MIDI orchestration examples opened up a whole new world of musical exploration for me. Highly recommended.
