From a musician's point of view, all music created so far belongs to just three kinds: rock, jazz and academic.
1. Academic music has main characteristic of being notated "on sheets", though there are three schools of academic music thought:
3. Rock music ranges from pop to extreme metal, from acoustic to electronic and its main characteristic is presence of vocals in most tracks though there exist entire subgenres entirely instrumental. Mostly recorded as performance by artists grouped into bands, though there exist entire subgenres entirely preformed solo.
In addition to these three performed genres, there is also a "produced" kind, of which it is possible to distinguish:
1. Academic music has main characteristic of being notated "on sheets", though there are three schools of academic music thought:
- European AKA "7 tones" recorded on 5 lines with dots and lines, started in Ancient Greece by Pythagoras;
- Ethiopian (Abyssinian Church tradition mostly, though Yared has created an independent universal system which is also the youngest, less than 2000 years old);
- Indian (using very different training and recording approach reaching prehistorical times)
- All the rest was summarized by musical theorists as "Natural tones" AKA pentatonic system, to which belongs absolutely every traditional ethnic music including so-called "classic" Chieese.
3. Rock music ranges from pop to extreme metal, from acoustic to electronic and its main characteristic is presence of vocals in most tracks though there exist entire subgenres entirely instrumental. Mostly recorded as performance by artists grouped into bands, though there exist entire subgenres entirely preformed solo.
In addition to these three performed genres, there is also a "produced" kind, of which it is possible to distinguish:
- Electronic music based on samples (of every other genre mentioned above and below, and also of non-human generated sounds, including e.g. "musique concrete"), part of this genre is actively applied by live performers, but the rule is simple: even Aphex Twin who has recorded a cello composition from own sound created with this instrument has... never learned to play cello, just its samples;
- Electronic music based on programming from which its differentiation from the above mentioned three genres has started, as academic composers have themselves created electric instruments sometimes, but their music was still requiring a human performer;
- Acapella, including from spoken word to rap: differs from the rest by using a unique internal human instrument, though vocals are used from chanting over a riddim and samples in hip-hop subgenre of rock to an academic quire, but can't be called music due to similar limitation as electronica: they are intangible.
