In Psalms King David writes to the chief musician , who is the chief musician?

There is no Christian bible. What we call the Old testament is the Tanach (Torah, Neviim, and Ktuvim). The sections that mention King David are in the Book of Samuel (among others) which are part of Ktuvim (writings) – and that predated Christ by hundreds of years.

The so called Christian bible is sometimes referred to as the New Testament.

Maybe you are referring to the King James (or other later) translations of the Tanach, which were written with a decidedly Christian spin 1400 years after they were originally released.

But the David section is very definitely, and in no way Christian whatsoever.

But

It’s in my bible… just a name of the chief musician would be welcome.

That would be David.

@Cruiser “That would be David.”

As in Lee Roth.

Asaph

@Darth_Algar Diamond Dave indeed!

@talljasperman The Chief Musician, according to 1 Chronicles 16:4–5, is Asaph, appointed by David to be the chief over all musicians in the Meeting Tent, before the Tabernacle.

It would be any music director associated with a reading of the Psalms.
Think of stage directions found in plays.

The guy who discovered the secret chord
That David played, and it pleased the Lord.
But you don’t really care for music, do ya?

…the baffled King composing “Hallelujah!”
