Syntagma Musicum is a book by the German musicologist Michael Praetorius, published in Wittenberg and Wolfenbüttel in three parts between 1614-1620. It is one of the most commonly used research sources for the music theory of the seventeenth century. The second work De Organographia illustrates and describes musical instruments and their use; becoming a valuable resource for the research and reconstruction of early instruments.
The three volumes (a fourth was in progress but never published) were:
- I: Musicae Artis Analecta
- II: De Organographia
- III: Termini musici
- Online edition at Internet Archive (vols. 2 and 3 only)
- English translation: De Organographia, Parts III – V with Index
