What Is Sound?
Sound is a vibration that travels through the air to your ear. Learn the four properties of every musical sound: pitch, duration, intensity, and timbre.
All lessons
Pitch in Music
Pitch is how high or low a sound is: fast vibrations make high sounds, slow vibrations make low sounds. Learn to hear pitch and understand frequency.
Duration in Music
Duration is how long a sound lasts, from a ringing bell to a quick clap. Learn how long and short sounds combine to create rhythm in music.
What Is Intensity in Music?
Intensity in music is how loud or soft a sound is, set by the amplitude of its vibration. Learn to hear it, see it as a wave, and control it as you play.
What Is Timbre in Music?
Timbre is what makes a piano and a violin sound different on the same note. Learn how sound color works, where it comes from, and how to hear it fast.
