'Musical' in the Bible

She looked, and there was the [young] king, standing by his pillar at the entrance, and the captains and the trumpeters were beside him. And all the people of the land were rejoicing and blowing trumpets, and the singers with their musical instruments were directing the [singing of] praise. Then Athaliah tore her clothes and cried, “Treason! Treason!”

and his brothers, Shemaiah, Azarel, Milalai, Gilalai, Maai, Nethanel, Judah, and Hanani, with the musical instruments of David the man of God. And Ezra the scribe went in front of them.

It is a good and delightful thing to give thanks to the Lord,To sing praises to Your name, O Most High,

Yet even lifeless things, whether flute or harp, when producing a sound, if they do not produce distinct [musical] tones, how will anyone [listening] know what is piped or played?
