2. Intervals, Scales, Tuning and Melody Melody Pitches, one after the other, which form a musical idea (a “tune”) Scale Ordered Set of Pitches Tuning Precise Frequencies (Colors the Scale) Supporting Raw Material Intervals

3. Tuning System a way to select the frequencies of pitches to form intervals, scales and chordsa way to select the frequencies of pitches to form intervals, scales and chords in tune = in focusin tune = in focus

4. [ii:34] In Tune = In Focus OUT OF TUNE (with fast beats) IN TUNE (beats disappear)

5. Beats (Beating) a periodic cancellation and reinforcement between waveforms as they interfere with each othera periodic cancellation and reinforcement between waveforms as they interfere with each other given two frequencies, 440 and 442 Hertz, the ear hears a single tone of 441 Hertz, fluctuating in amplitude at 2 beats per secondgiven two frequencies, 440 and 442 Hertz, the ear hears a single tone of 441 Hertz, fluctuating in amplitude at 2 beats per second [ii:35] sine waves at:[ii:35] sine waves at: 440 Hertz440 Hertz 442 Hertz442 Hertz 440 and 442 Hertz together (with 2 beats per second)440 and 442 Hertz together (with 2 beats per second)

11. IntervalInterval the distance between two pitchesthe distance between two pitches the pitches of an interval may sound at the same time or one after the otherthe pitches of an interval may sound at the same time or one after the other
