Even if you have no musical ability, utter the names of the Lord with feeling and love. There is no greater means of God-realization in the Kali Yuga than chanting the names of the Lord. Remembering the Name is the panacea. When the name is chanted as a song set to music, it delights the heart immensely. They do not experience the intense yearning expressed in the stanzas.
Some actors are able to pronounce the words loud and clear, but without any depth of feeling.
But when the names are sung melodiously they appeal to the hearts of the singers and the listeners. Even non-believers and agnostics nod their heads in appreciation when they listen to devotional music. A song sung melodiously tugs at the heart-strings. The word of a song can be expressed in prosaic manner which has no appeal to the listener. Such sweetness is contained in the song when it is rendered melodiously.
