Several of Robert Browning's Dramatic Monologues [fiction though in verse] attempt to describe the musical technique and experience. "Master Hugues of Saxe-Gotha" seems to me the most impressive, relating the music the organist is playing to the great building in which he is playing it; tho it ends with the frustration of the narrator, whose thought processes are interrupted by his light going out just as he is reaching his architectural-analogical conclusion as to how the composer of the "mountainous fugues" gets his effects.

'Abt Vogler' and 'A Toccata of Galluppi's' are two other of his poems on the same lines; tho this last is more about the listener's interpretation, and the effect the music has on him, than any analysis of the music itself; and in 'Abt Vogler', the music becomes a symbol of RB's preoccupation with the impossibility of finding perfection on this Earth ~ "On the earth the broken arcs; in the heaven, a perfect round" ~ and the necessity of death to find that perfection:~ "have dared and done, for my resting-place is found,
The C Major of this life: so, now I will try to sleep".

But I think these 3 poems will give some such verbal/musical enlightenment as this thread appears to seek.
