Isn't it clever?
Firstly - Musica is the Latin word for 'the art of music, or music itself (including poetry).
Secondly - If you study at this place, I suppose you will get plenty of music.
Thirdly - It calls to mind the expression aplenty. Dictionary.com defines this as either an adjective or an adverb:
adjective in sufficient quantity; in generous amounts (usually following the noun it modifies); He had troubles aplenty. adverb sufficiently; enough; more than sparingly: He howled aplenty when hurt.Correctly, the advertisement places the word 'aplenty' after the noun, 'musica'.
And, fourthly, cleverest of all in my opinion, the music school is on
I love to see language used so creatively.
