About Music Facts
Music is both physical vibration and human interpretation. The same sound wave can be measured with instruments, but its meaning depends on culture, memory, expectation, and context.
Sound Needs a Medium
Ordinary sound waves travel through matter.
Learn MoreFrequency and Pitch
Faster vibration is generally heard as higher pitch.
Learn MoreLoudness Is Logarithmic
Decibels use a logarithmic scale.
Learn MoreHearing Can Be Damaged
Very loud sound can permanently injure sensory cells in the inner ear.
Learn MoreOctaves
Notes an octave apart have frequencies in a two-to-one ratio.
Learn MoreTuning Systems Differ
There is no single universal tuning system.
Learn MoreMusic and Memory
Music can strongly cue memory.
Learn MoreTechnology Changes Style
New instruments and recording tools create new genres.
Learn MoreSound Needs a Medium
In a vacuum there is no air to carry normal sound waves.
Frequency and Pitch
Human pitch perception is complex and depends on harmonics and context as well as a single frequency.
Loudness Is Logarithmic
This matches the enormous range between the quietest and loudest sounds humans can perceive.
Hearing Can Be Damaged
Musicians and audiences use hearing protection when exposure levels are high.
Octaves
Many musical cultures treat octave-related pitches as closely connected.
Tuning Systems Differ
Equal temperament is common in modern Western instruments, while other traditions divide pitch differently.

Rhythm, repetition, melody, and emotional association make songs unusually memorable.
Technology Changes Style
Electric amplification, synthesizers, samplers, drum machines, Auto-Tune, and digital workstations all influenced how music sounds.
