'Notes' in the Bible

And at the first notes of song and praise the Lord sent a surprise attack against the children of Ammon and Moab and the people of Mount Seir, who had come against Judah; and they were overcome.

“Will all these [victims of his greed] not take up a taunting song against him,And in mocking derision against himSay, ‘Woe (judgment is coming) to him who increases that which is not his—How long [will he possess it]?And [woe to him who] makes himself wealthy with loans.’

Even inanimate things that produce sounds—whether flute or harp—if they don’t make a distinction in the notes, how will what is played on the flute or harp be recognized?
