Boyd’s Bible Dictionary:
(muse). Anciently known (Gen. 4:21; 31:27; Job 21:12). Vocal and instrumental, reached highest perfection in temple choirs (2 Sam. 6:5; 1 Chron. 25). Usual instruments, harp, timbrel, Psalter, trumpet, flute, pipe, and so forth.
“Music, Musicians, Musical Instruments” From Concise Bible Dictionary:
The harp and the organ, or pipe, were in use as early as Genesis 4:21. Laban, when chiding with Jacob for secretly leaving him, said he would have sent him away “with songs, with tabret, and with harp” (Gen. 31:27). The monuments show that the Egyptians had various musical instruments, the Israelites, therefore, if they had not known their use before going into Egypt, could have learned it there. When Moses sang the song of triumph at the Red Sea, Miriam answered with a tabret in her hand; and Samuel told Saul that he would meet a company of prophets with a psaltery, a tabret, a pipe, and a harp (1 Sam. 10:5).
There must have been with these prophets some knowledge of music, which doubtless under David was further cultivated and devoted to the service of God, their music being intimately connected with temple worship. He had several companies of singers, and players on instruments, which are often mentioned in the Psalm. As these were indited under the guidance of the Holy Spirit, we may conclude that this way of celebrating the praises of God was in accordance with the dispensation that then was. Such an exhortation as “Praise Him with the psaltery and harp,” is beautifully in place in the Psalms; but in the New Testament dispensation it is, “singing and making melody in your heart to the Lord”; and “I will sing with the spirit, and I will sing with the understanding also.” “They that worship Him must worship Him in spirit and in truth.”
In the headings of fifty-five of the Psalm the words occur, “To the chief musician”; the word is natsach, and simply means “to the chief or the leader,” and may therefore apply as much to the singers as to the musicians. The musical instruments are considered under their various names.
“Overseer” From Concise Bible Dictionary:
Used in scripture for any one that had the oversight or leadership of others (Gen. 39:4-5, and more). In the AV. it is once the translation of έπίσκοπος, (Acts 20:28), which is elsewhere translated BISHOP.
“Singing” From Concise Bible Dictionary:
In the Old Testament we find there were courses of singers, and there were some who were “taught to sing praise.” Instruments were also appointed for the singers (1 Kings 10:12). In Habakkuk 3:19, at the end of the prophet’s poetical “prayer,” it says, “To the chief singer on my stringed instruments.” “The singers went before, the players on instruments followed after; among them were the damsels playing with timbrels” (Psa. 68:25).
Such organized choirs have no place in the New Testament They that worship God “must worship Him in spirit and in truth.” This also applies to the singing: “I will sing with the spirit, and I will sing with the understanding also” (1 Cor. 14:15; compare 1 Cor. 14:26). “Be filled with the Spirit, speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody [or chanting] in your heart to the Lord” (Eph. 5:19). “In psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord” (Col. 3:16). There will be singing in heaven (Rev. 5:9). Singing and PRAISE naturally go together. At the institution of the Lord’s supper they “sang a hymn,” margin “psalm,” ὐμνέω (Matt. 26:30). The same word is translated “sang praises” unto God, when Paul and Silas were in prison (Acts 16:25); and the Lord sings praise in the midst of the assembly (Psa. 22:22; Heb. 2:12).
