What you will learn

Match the sound source to the result you want

  • Recognize common acoustic sources such as piano, guitar, strings, and flute.
  • Recognize electronic sources such as synth leads, synth pads, synth bass, and drum machines.
  • Keep electric guitar and electric bass distinct from synthesized sources.
  • Combine acoustic and electronic layers without losing each instrument’s role.

Mechanical sound sources

Acoustic instruments begin with a vibrating physical body

Listen for strings, air, skins, wood, and metal

Acoustic guitarplucked or strummed strings and a resonant body
Acoustic pianohammers striking strings inside the instrument
Violin or stringsbowed or plucked strings
Flutea breath-driven wind sound
Brasslip vibration through a metal tube
Hand percussionstruck, shaken, or scraped physical surfaces

Programmed rhythmdrum machine

Electronic percussion and sequenced beats.

Do not collapse the categories

Electric guitar is not another name for synthesizer

Name the source when the distinction changes the performance

An electric guitar begins with vibrating strings captured by pickups and amplified. A synthesizer generates an electronic signal. Both can be processed heavily, but they start from different sources and suggest different performances. If the distinction matters, name it.
