The video "Our Musical heritage: Music of the Middle Ages" is a very old video production. It seem this video was prepared with very low budget. It has poor representation, poor images and poor creativity. It does not present real instruments, so it is not well documentated. It lacks of historical contents, it does not present all the spectrum of medieval music. Spanish Jewish medieval music is not present as well as mozarabic music and or intrumentation. The recording is also very poor. It would be a good idea for film makers to create a well documentated video on this topic. The plastic appearance of the film is so old it jumps on your TV.
