Question

how did frog try to impresse the nightingale when he met her for the first time?

Answer 1

He used some gud music syllables for her
He said that she sung gud .he elaborated and explained notes and pitches of her music which likely bounced off the poor nightingle. He also proposed her to be her student and she will become a successful singer one day by her own
Thus his show off worked and the nightingle was caught in his music skill 
this was how he impresed her for the first time
