‘We played the flute for you, yet you did not dance; we wailed in mourning, yet you did not weep.’

It is similar for lifeless things that make a sound, like a flute or harp. Unless they make a distinction in the notes, how can what is played on the flute or harp be understood?

They are like children sitting in the marketplace and calling out to one another, ‘We played the flute for you, yet you did not dance; we wailed in mourning, yet you did not weep.’
