1. A concept piece is entirely determined by one trenchant idea.
2. The idea is a machine that produces the work of art. The process should have required no intervention, it should take its own course. (LeWitt 1967)
3. The concept-machine today is above all the algorithm.
4. The processing-material of the machine today is the total archive.
5. Details, rhetorical means, and formal design are usually only suitable in the form of readymades or by means of chance generators.
6. For each work of art that is performed physically, there are many unperformed variants. (LeWitt 1967)
7. The sensual appearance is only one aspect of the work, to which more or less value can be granted.
8. Each piece of New Music has conceptual aspects. (Spahlinger 2009)
9. Not all ideas have to be implemented. (LeWitt 1967)
10. On the other hand, one can also compose a detailed form out of many different concept-variants or -pieces. Enrichment with jokes is also OK.
11. A banal idea cannot be rescued by a beautiful and expressive design. However, it is difficult to bungle a good idea. (LeWitt 1967)
12. A good idea can be bungled through a beautiful and expressive design.
13. Ideas are the most expressive and most beautiful of all.
14. Improvisation is rarely musical concept-art, least of all when the improvisation is good.
15. Musical conceptualism can be considered as a minimalism.
16. An idea is the "smallest possible whole". (Musik 1916)
17. Music does not have to be self-explanatory. The composer does not need to shy away from intermedial ingredients (text, video, performance), indeed it makes perfect sense to articulate them (no hiding important information in the program notes).
18. Dare to make public/publish the even slightest idea if you believe there’s something in it. But give it a proportionate effort (no more than a small text for a small idea).
19. A piece of conceptual music does not have to be completely heard.
20. Music is only New Music when it raises the question: is this actually music? (Spahlinger 1992)
21. The more unmusical, the better.
22. Out of conceptualization emerges contextualization. (Weibel 1993)
23. No concept without conceptualism.
