When the heart is in tune, its trembling chords
Swell the name of Jesus;
Then the strings that were mute with joy expand
At the touch of His master hand.

Refrain:
Sweetest music, sweetest music,
When the blessed name we love-
From the full heart breaks;
Sweetest music, sweetest music,
When the melody of song He wakes.

When the heart is in tune, its only song-
Praise and love to Jesus;
With a holy delight its chords expand
At the touch of His master hand. [Refrain]

When the heart is in tune, it wearies not,
Still it sings of Jesus;
For its strings are in tune with harps above
And the songs of redeeming love. [Refrain]
