Serialism is a form of Expressionism in music – that is showing extremes of emotion in music. Expressionist composers believed that it was impossible to convey emotion in music when constrained with traditional harmony and phrase structure.
Serialism is a technique of ensuring that all 12 notes of the chromatic scale are sounded as often as possible. All 12 notes are given equal importance so the music avoids any sense of tonality or traditional harmony.
The A Level class used this technique and each wrote a piece of Serialism based on a tone row – their own order of the 12 notes.
This is how they sound.
“The Twelfth Toe”
“A Fragmenty Fantastique”
