The available Ellen White Estate book sources do not directly address the question of whether professional musicians should be paid in a modern, secular sense. However, there are some relevant principles and references: - There is no explicit statement found that says "professional musicians should be paid." - There are references to singers and players of instruments being present in worship and that their service is important (see Education, p. 307.2; Testimonies for the Church, vol. 9, p. 144.1), but no direct mention of payment for musicians. - There are strong statements about the importance of fair remuneration for ministers, colporteurs, and workers in God's cause, emphasizing that "the laborer is worthy of his hire" (Gospel Workers [1892], p. 200; Testimonies for the Church, vol. 9, p. 250.1; Gospel Workers, p. 228.1). - There is a general principle that those who labor in God's work should be compensated fairly, and it is considered unjust to withhold proper wages from them. In summary: While Ellen White's writings emphasize fair compensation for those who labor in ministry and related church work, there is no direct statement about paying professional musicians. The principle of fair remuneration for service rendered, especially in the context of church work, is affirmed. If musicians are serving in a professional capacity for the church, the same principle of fair compensation could reasonably be applied. If you are seeking a more specific answer or a statement about secular/professional musicians outside of church work, there isn't adequate information in the available sources to answer this question.
