1 The χορηγία was one of the λητουργίαι, or public duties, imposed upon the richer citizens by the state. A Choregus had to equip and train a chorus for one of the annual festivals, in this case the Thargelia, held in honor of Apollo and celebrated on the 7th of Thargelion (May 1st) by a competition between choirs of boys selected from the ten tribes, which were grouped in pairs for the purpose.
2 Probably this is the Pantacles who appears as a lyric poet in a choregic inscription of the period ( I.G. i(2). 771). Aristophanes also refers jokingly to a Pantacles who got into difficulties with his helmet at the Panatheniac procession on one occasion (Aristoph. Frogs 1036: first staged in 405); but it is not certain that he was the poet.

4 i.e. the Great Dionysia (τὰ ἐν ἄστει Διονύσια), celebrated every March with a procession, choruses of boys, and tragic and comic performances. The speaker had undertaken the training of a chorus for the festival in some previous year.
5 The Choregus was empowered to inflict fines upon parents who refused to allow their sons to perform without good reason. The “pledges” mentioned would presumably be exacted from parents who did proffer some excuse. If the excuse proved unsatisfactory, they would forfeit their money.
