As technology advances, the tools at our disposal are more numerous and varied. Beyond the traditional analog instruments that send pulses of air-pressure vibrating through the atmosphere at various frequencies, we now use all sorts of devices/systems that technically make no sound at all (until these devices/systems are connected to speakers and the atmosphere is disturbed and our ears & brains experience the sound).
There are all sorts of sounds that we can create. . . .tapping a pencil against a coffee mug. . .drawing a horse-hair bow across a tightly wound metal string. . .humming a melody. . .recording "found sounds" and playing them back in a sequenced manner. But when do sounds become music?
Be it EDM, hip-hop, country, rock 'n roll, blues, jazz, opera. . .whatever the means (sampling, loops, singer-songwriter, found-sounds, synths, strings, full-orchestra, etc.). . .no matter the venue/environment (in the studio, an arena, an opera house, a subway platform). . .with or without lyrics. . .the difference between sound and music is the human element. Specifically - human emotion. . . .emotion that the performer places into the music and - equally important - the emotion that the listener experiences.
Often the artist successfully expresses their feelings and develop music that stirs up those same feelings (or similar feelings) in others. Sometimes - however - it takes an independent and honest ear (and an honest heart) to provide a fresh perspective and point of view. For many artists, it's only with that perspective and positive support that they journey to those places that they wouldn't reach on their own - where noise becomes music.
