Melancholia comes from a suite of pieces I composed back in 2012-2013 called, The Year of the Guitar. My goal for composing these pieces was to compose a group of guitar pieces for the intermediate-level guitarist. This particular one uses a lot of artificial harmonics, which is a really cool effect you can get on the guitar.
A Beam of Light on a Yellow Flower is a piece I composed for my guitar school found at my website. I wanted to compose a piece where you would alternate between melody (played by the fingers) and a simple bass (played by the thumb).
Harmonics are a cool effect on the guitar and I try to incorporate them as much as I can in my originals and arrangements. This etude I composed includes natural and artificial harmonics. It also includes a technique that I call, harp harmonics. It gives the impression of a harp.
These are all techniques commonly called extended techniques. Extended techniques involve producing sound with an instrument in an unorthodox way.
