Adam Clarke Bible Commentary

Asaph - This person, with Heman, the sons of Kora, Ethan, Jeduthun, etc., are celebrated in these books, and in the Psalms, for their skill in singing, and the part they performed in the public worship of God. It is very likely that their singing was only a kind of recitative or chanting, such as we still find in the synagogues. It does not appear that God had especially appointed these singers, much less any musical instruments, (the silver trumpets excepted), to be employed in his service. Musical instruments in the house of God are, at least under the Gospel, repugnant to the spirit of Christianity, and tend not a little to corrupt the worship of God. Those who are fond of music in the theater are fond of it in the house of God when they go thither; and some, professing Christianity, set up such a spurious worship in order to draw people to hear the Gospel! This is doing evil that good may come of it; and by this means, light and trifling people are introduced into the Church of Christ, and when in, are generally very troublesome, hard to be pleased, and difficult to be saved.
