  +Most browsers will not allow _any_ audio to play until a user clicks something (think play button). The above example won't play unless invoke `resume` on the Tone.js context.

  +```javascript
  +document.querySelector('button').addEventListener('click', () => Tone.context.resume())

  #### Tone.Synth
  [Tone.Synth](https://tonejs.github.io/docs/#Synth) is a basic synthesizer with a single [oscillator](https://tonejs.github.io/docs/#OmniOscillator) and an [ADSR envelope](https://en.wikipedia.org/wiki/Synthesizer#ADSR_envelope).
