In the first level there are plucked strings, bowed strings in the second, harps in the third, psalteries in the fourth, plucked strings in the fifth, aerophones in the sixth, percussion in the seventh, aerophones again in the eighth, and, finally, bowed strings in the last level. This tells us a lot about the musical concern of the representation, as instruments are not arbitrarily arranged, but carefully placed so that the hypothetical sound of the "orchestra" is acoustically balanced.
Musicological reliance
The Portico shows rather atypical instruments compared to other contemporary representations. the musicological reliance of these representations is usually questioned but, according to Mary Remnant in her "History of Musical Instruments" (1989), "The argument of the artistic licence or of the mistake is relevant indeed, and a final test would be required in order to verify whether the instrument depicted could be played. If it couldn't, the reason could either be the limited knowledge of the artist or just that he never tried to be meticulous or precise, as we can imagine from so many fantastic drawings and representation available. Sometimes a correct instrument is held in an impracticable position due to symmetrical requirements in the composition or to some other reason. For instance, an angel in the ceiling of a church may be pointing his instrument downwards so that it can be seen from below, while a wooden or stone carved instrument can be sustained in an adapted position to prevent it from breaking. Anyhow, on many occasions, obvious artistic licences or mistakes do not necessarily mean that the whole instrument is false". We could add to the illustrative text by M. Remnant that, on many other occasions too, extremely sophisticated and precise luthier details can be observed in spite of the obvious difficulties involved for the artist.
The truth is that the work of those carvers representing scenes, attires,
architectures and also musical instruments, gives us the opportunity to
reproduce them and, in consequence, to listen to the sound that accompanied
the festivals and celebrations of that period.
The Pórtico de la Majestad is a time trip and allows our eyes to rest on the same stones our ancestors used to gaze while crossing the Collegiate square during their daily activities or when, on the great events, they became entranced, looking up at these sculptures, astonished at the skills of their makers. It is a joyful event for us to be able to enjoy them in our days.
