Cacti in the Window

Thank you for yesterday's stars, and the expressions of scepticism and hope on the theme of graffiti.
Rain this morning so listened on iPlayer to the start of the first night of the Proms and Felix Mendelssohn’s Hebrides Overture - Fingal’s Cave. Mendelssohn was greatly affected by his visit there in 1829 and immediately jotted down the opening phrase of the overture which came into his head. I immediately found it captivating and quite extraordinary.This is sometimes considered an early example of a tone poem.
A Tone Poem or synphonic poem is described in Wikipedia as:
“ a piece of orchestral music, usually in a single continuous movement, which illustrates or evokes the content of a poem, short story, novel, painting, landscape, or other (non-musical) source.”
Well, there you go, if like me you didn't already know!
