I sang in many church choirs during the last 50 plus years.
Churches had gifted choir directors, choir members and soloists.

Most directors were dedicated, cordial and appreciative. I remember only once being required to audition for a church choir.
Back in the early 1970’s, J. Lamar Alexander was serving as choir director at the First Baptist Church of Lake Providence, Louisiana. He had me sing notes of the scale. I’m surprised that I got up the courage. I’d say he was a master at his craft…
He mastered the traditional form of worship service.
Lamar Alexander believed in call to worship opening selections. To this very day I recall the holy hush following our offerings of ‘The Lord is in His Holy Temple.’
“But the Lord is in his holy temple: let all the earth keep silence before him (Habakkuk 2:20 KJV).”
The lyrics, based on Scripture, called us to worship, submission and praise.
