Document Summary
Lecture 4: this is ideal, no echo, no reverberation, you want this so effects can be added later. You can take a dry space and mimic all sounds in this area. Sonogram: recall: frequency vs. time, intensity represented by color. Recall: overtones double in frequency fundamental, then triple, etc. Sympathetic vibration: when one string holds the sound of another after it has been released. Overtone example: what if you have o4 = 1500 hz. You know o4 is f x 5, so f = o4/5: f = 1500/5, f = 300 hz, then you go from there to fill in everything else. Overtone example: what if instead of frequencies, you are using note names (ex: fundamental = You know that overtone series goes: octave, perfect fifth, perfect fourth. One reason why some instruments project better than others has to do with the overtone structure and the spectral mix of the instruments structure: ex: why trumpet sounds are louder than clarinets.
