Canon a 4 for String Quartet in F minor.

Probably the shortest canon I have ever written in terms of duration, as I found most suitable to dedicate it as a gift to my mother both on account of this year's Mother's Day and her own birthday falling by the end of the month.

Enjoy!

Wow
It sounds very intense and spectacular, with 4 voices...
The truth is that it catches you in a non-stop progression. I think the shortness of it benefits it given its textural intensity.
The sound of the strings sounds like it's a podo “dejado” (I don't know how to explain it.... in Spanish “dejado”). Is it some effect.

Greetings, and congratulations to your mother....
