Calvin on psalm singing

‘But what then ought to be done? Let us have songs that are not only decent but holy. These will incite us to pray and praise God, to meditate on his works, in order to love, fear, honour and glorify him. But what Augustine says is true, that no one can sing things worthy of God, unless he has received them from Himself. Therefore, after we have sought on every side, searching here and there, we shall find no songs better and more suitable for our purpose than the Psalms of David, dictated to him and made for him by the Holy Spirit. But singing them ourselves we feel as certain that God put the words into our mouths as if He Himself were singing within us to exalt His glory. Hence Chrysostom exhorts men, women and little children alike to become accustomed to sing them, in order that their practice might be as a meditation to associate themselves with the company of angels… only let the world be well advised, that instead of the songs partly vain and frivolous, partly dull and foolish, partly filthy and vile, and consequently wicked and hurtful, which it has hitherto used, it should accustom itself hereafter to sing these divine and heavenly songs with good King David,’ (John Calvin, Epistre au lecteur in La forme des prieres et chants ecclesiastiques, in Calvini Opera, 6:171ff.).
