We can hear a wide range of sound frequencies, but we don’t use them all to make music. We select some discrete set of them as our notes to form what we call a scale. We try to build scales in such a way that combinations of notes on the scale are harmonious and can be played together. Scale Lab allows you to explore, measure, create and modify both individual sounds and musical scales. This exhibit covers the fundamentals of sound, perception of consonance and dissonance and the creation of scales from single tones.
