Beauty of music comes not from the rhythm or notes, harmony or melody. Not in rarely perfectly played dissonance or commonly heard resonance nor eloquent words or enticing human voice.
No matter how you use these things, no matter how great a master musician. You may create what sounds good and convincing but if music has no emotion no cause for expression it'll sound empty and dull, spread apathy even slight depression.
Sing through any noise, beat, clatter through humming, whistling, or just simple chatter. Doesn't matter, as long you do it to express what you feel inside people will only hear beauty something real and alive. They might be drawn to hear or flee in fear, but if a song invokes any response then it had meaning, something inside the authors heart. We all have a story or lessons we have learned.
All strings in our hearts that once plucked play a song. Once heard other hearts will start singing along each adding their own beauty. Imagine 20 souls expressing the same music with their own unique song, this is how i picture heavenly music. Music does not make beautiful emotions, emotions make beautiful music.
