Syntagma Musicum is a book by the German musicologist Michael Praetorius, published in Wittenberg and Wolfenbüttel in three parts between 1614 and 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
