妙法蓮華經玄贊 7.377

7.377

贊曰：四作樂。「伎」音渠倚反，藝也，女樂作妓。有作「伎」，立也。經文乘便，故說乃至終恒樂供養。

The Eulogy says: Fourth, playing music. The character 伎 is pronounced with the fanqie qú-yǐ, meaning arts or skills; female musicians are written 妓. Some write 伎, meaning to stand. Taking advantage of the context, the sūtra text therefore states that all the way to the end they constantly made music offerings.
