Note 32 at Eph. 5:19: The Greek word that was translated "songs" here is ODE. This Greek word has been transliterated into the English language and "ode" is still used to denote "a lyric poem often addressed to a praised object or person and characterized by exalted style" (New Am. Her. Dict.). So, the word "songs," as used here, is speaking of uplifting songs that praise the Lord. The connection with the word "spiritual" is specifying "non-carnal" or songs that deal with spiritual truths. The Greek word used for "hymns" means "to celebrate" or "a religious ode." And the word for "psalms" is specifying one of the poems which was set to music in the book of Psalms.

Therefore, this verse is instructing us to praise the Lord with songs from the scripture, hymns of a traditional nature, and other songs about spiritual things that uplift the Lord.

Note 33 at Eph. 5:19: The English phrase "making melody" was translated from the Greek word PSALLO which means, "to twitch or twang, i.e. to play on a stringed instrument" (Strong). This symbolism is probably where we get the idea of striking a chord in someone's heart. When we worship the Lord from our heart, it is like playing a musical instrument to the Lord. Regardless of our physical ability to play an instrument, everyone can make melody in his or her heart to the Lord.
