Lecture
This lecture covers the concepts of pitch and frequency in sound, explaining how pitch is related to the highness or lowness of a sound and how it affects our ability to recognize melodies. It also discusses the Frequency Difference Limen (FDL) and its role in distinguishing pitches. The harmonic pitch, timbre, and the effects of phase differences on harmonics are explored. Additionally, the lecture delves into beats, vibrato, and tremolo in sound perception, as well as the ear's selectivity towards different frequencies and musical scales.
