David told the leaders of the Levites to appoint their brothers as singers to sing joyful songs, accompanied by musical instruments: lyres, harps and cymbals. I Chronicles 15:16
Did you know a human may well be the only thing in God’s creation that sings? I’ll admit that the point is arguable. It depends on exactly what you mean by “sing.” However, by all accounts our human experience of this phenomenon is unique. Birds chirp various tones, but they are bound to repeat these same tones and can never make up any other. Many animals express emotion by various vocalizations, but the purr of a cat or the bray of a lonely donkey can hardly be called music. Even angels are said to speak rather than sing out their praise (Luk. 2:13-14). God can sing (Zep. 3:17) and people sing, but the rest of creation? Not really.
Happiness, joy and celebration are closely tied to music. Before the temple was built, David set up a system where music would be flowing 24/7 (I Co. 9:33) as they sang day and night in the house of the Lord. And, in the early church (as today) music was a vital part of every gathering. They even sang to each other (Eph. 5:19) and no one seemed to bother with whether one could carry a tune.
Music is one of the few things that carries a double blessing. When we praise, it lifts the spirit of others and then ricochets to lift our own heart as well. Got a bad mood going and want to break the spell? Sing! It can be the fastest route to restoring joy and a positive attitude.
