Tonic accents emphases on pitch. By definition, a tonic accent in classical music is the attention given on a note with a particularly high pitch. Tonic accents in general refer to the pitch that a sound has.
Agogic accents emphases on duration. A variation on the duration of a note will make the beat stronger, where otherwise it would sound flat and without an accent.
Art. art was important back then. (I strongly suggest not looking up greek art, but if you are 18+ and really want to know, look it up.)
