Charles H. Spurgeon on Psalms 92:3

Upon an instrument of ten strings; with the fullest range of music, uttering before God with the full compass of melody the richest emotions of his soul. And upon the psaltery; thus giving variety to praise: the Psalmist felt that every sweet-sounding instrument should be consecrated to God. George Herbert and Martin Luther aided their private devotions by instrumental music; and whatever may have been the differences of opinion in the Christian church, as to the performance of instrumental music in public, we have met with no objection to its personal and private use. Upon the harp with a solemn sound, or upon meditation with a harp; as much as to say, my meditative soul is, after all, the best instrument, and the harp's dulcet tones comes in to aid my thoughts. It is blessed work when hand and tongue work together in the heavenly occupation of praise.

"Strings and voices, hands and hearts,

In the concert bear your parts:

All that breathe, your God adore,

Praise him, praise him, evermore."

It is, however, much to be feared that attention to the mere mechanism of music, noting keys and strings, bars and crotchets, has carried many away from the spiritual harmony which is the soul and essence of praise. Fine music without devotion is but a splendid garment upon a corpse.
