Surely [Build] Loudness level [Drop] Recognize those sounds? Listen [Spoken Verse] Some sounds appear higher or lower to our ears than others The term we use to describe this relative characteristic is pitch Pitch depends chiefly on the number of times each second That the air pressure fluctuation on your ear is repeated Listen as we cause a stretched string to vibrate 440 times a second Let's investigate what causes sound, listen [Build] Loudness level [Drop] Similarly Loudness level Listen Loudness level
