Albert Barnes Commentary Psalms 144:9

"I will sing a new song unto thee, O God: Upon a psaltery of ten strings will I sing praises unto thee." — Psalms 144:9 (ASV)

I will sing a new song unto thee, O God - There will be occasion in such a deliverance, or manifestation of mercy, for a new expression of praise. On the phrase, a new song, see the notes at (Psalms 33:3).

Upon a psaltery, and an instrument of ten strings - The word “and” should not have been inserted here. The idea is, “Upon a lyre or harp (Nebel) of ten strings, will I sing praise.” See the notes at (Isaiah 5:12); and notes at (Psalms 33:2).
