Chapter 1: Introduction to Magenta and Generative Art

1. Randomness.
2. Markov chain.
3. Algorave.
4. Long short-term memory (LSTM).
5. Autonomous systems generate music without operator input; assisting music systems will complement an artist while working.
6. Symbolic: sheet music, MIDI, MusicXML, AbcNotation. Sub-symbolic: raw audio (waveform), spectrogram.
7. "Note On" and "Note Off" timing, pitch between 1 and 127 kHz, velocity, and channel.
8. At a sample rate of 96 kHz, the Nyquist frequency is 96 kHz/2 = 48 kHz and the frequency range is 0 to 48 kHz. This is worse for listening to audio since 28 kHz of audio is lost on the ear (remember anything over 20 khz cannot be heard), and that sampling rate is not properly supported by much audio equipment. It is useful in recording and audio editing though.
9. A single musical note, A4, is played for 1 second loudly.
10. Drums, voice (melody...
