Every musical instrument has the ability to manipulate (to varying degrees)  the 3 properties of sound.
  • Pitch
  • Tone
  • Volume

The way in which each instrument does this is dependant on its physical design and structure. A guitar will always sound different to a trombone due to how each is constructed and how the sound is produced within them.

Every note played on any instrument is not just a single note, but a combination of strong and weak harmonics stretched across the audio spectrum. It is these differences in harmonic structure that defines the Timbre or Tone of an instrument.

Synthesisers are a good way to break down sound into simpler components so that we can get a grasp of how it all works at a fundamental level.

In this article we look look at the very basics of the components of a synthesiser and how they interact with sound at each point ultimately having the ability to completely hand craft and almost limitless variation of sounds.

The average synthesiser is made up of 5 stages. These are: 
  • Oscillator
  • Filter
  • Amplifier
  • LFO
  • Envelope
