Spontaneous - singing along to songs

Spontaneous need to be creative in some way, and I will do it in a variety of ways also. I can sing, whistle, hum hoo notes or whatever sound I like but I like that one, hum while whistling, do harmonic tongue clicks, hum while doing that, drum on my body, sometimes some spoken word.. generally be harmonic and a good accent that might even make the music sound better. Who knows?
