Kommentar zu Divrej Hajamim I 15:22

And Chenaniah, the leader of the Levites in song In what was he a leader? In בַּמַּשָּׂא, in raising [the voice in]song.

he would chastise in song He would chastise and reprove them concerning raising the voice in the melody of the song, whether to raise the voice or lower [it].

because he was an expert in raising [the voice] in the melody, and the expression of מֵבִין applies to the study of voice. A similar instance is found (below 25:7): “And their number with their brethren, trained in song to the Lord, every expert (מֵבִין) etc.,” and it is written (ibid. verse 8): “and they cast lots, etc.,...expert (מֵבִין) with student.”
