## Music Notation History
- Hand notation (western)
- Earliest examples in Nippur (Iraq) and Greece
- Neumes (650ad), Notation before 5 line staff. Was representative not specific
- Chinese use lute tableatures (100ad)
- 800ad - 1400ad development of early western music notation
- Chinese notation around 1425ad
- Printed music around 1500-1700, in Italy. First to do polyphonic music. Developed an international style of notation
- Computer aided notation (fonts, layouts, rules). Each element assigned a code. Until mid 1800s notation was mostly done by hand. During 1800s various machines to automate the process (typewriter)
- Keaton Music typewriter (1930s)
- Effingers music-writer in 1955 (amateurs and musicians)
- Max Mathhews at Bell Labs (Hiller, Isaacson built earliest synths ILLIAC, RCA)
- Only language was the native ones (punch cards, paper tape)
- Programs on IBM PCs appear that do notation
- Standardization begins to change the landscape
	- Mac brings graphics to mainstream
	- Midi standardized
	- Sonata Adobe font
	- Laser printers
- MIDI facilitated the way devices speak to each other in regards to music information
- Finale and Sibelius emerge as big notation software
- Cloud based solutions emerge as competitors
## Acoustics
- Frequency - Pitch (Hz)
- Amplitude - Loudness (dB)
- Envelope - Attack -> Decay -> Sustain -> Release, envelope is the entire pattern
- Harmonic Spectrum - The entire tone of a note (fundamental and overtones)
- Timbre - Color of the sound
- Fundamental - Fundamental note in character of a note (not the partials)
- Overtones - Tones above the fundamental (partials)
- Pitch (Musician Name)
- Loudness (Musician Name)
- Articulation
