Four-part canon “Introite portas eius” (Title: “Canon. ad subdiateßeron, sub-diapason, et sub-diapason-dateßeron) [Storia I, 54]

Canons are short musical compositions designed so that the same melody is sung by multiple voices at staggered intervals. Most of Mozart’s canons were composed in Vienna, where there was a strong tradition of private music-making. It appears that Mozart occasionally wrote the texts for these himself. Canons without text and those with Latin texts were also used in counterpoint instruction (see Appendix H).
