Primitives

Play chord composed from SoundNote

Sound[SoundNote[{"E", "G#", "B"}]]

Play D Major scale up and down doubled in up-octave

major = {2,2,1,2,2,2};
SoundNote[{#, # + 12}] &/@ Accumulate[Join[{2}, major, -major]] // Sound

It is possible to play the sound programmatically without a widget using FrontSubmit

EventHandler[InputButton[], Function[Null,
  FrontSubmit[Sound[SoundNote[RandomInteger[{0, 12}]]]]
]]

or use EmitSound

tip

If you want to continuously stream raw sound data, consider to use PCMPlayer
