MusicNote[pitch]
MusicNote[pitch, duration]
MusicNote[properties]

represents a symbolic musical note. pitch can be a named pitch, a MIDI pitch number or a MusicPitch object. duration can be a number, a named duration or a MusicDuration object.

MusicNote["G4", 1/2]

Equivalent property form:

MusicNote[
  <|
    "Pitch" -> MusicPitch["G4"],
    "Duration" -> MusicDuration[1/2]
  |>
]

Useful properties include "Pitch", "Duration", "SoundVolume", "Style" and "TieType". Retrieve properties using the normal Wolfram property syntax:

note = MusicNote["C4", 1/4];
note["Pitch"]
note["PropertyAssociation"]

Playback

MusicNote is accepted directly as a Sound primitive:

Sound[MusicNote["C4", 1/4]]

Sequences can mix notes, rests and chords:

Sound[{
  MusicNote["C4", 1/4],
  MusicRest[1/8],
  MusicNote["E4", 1/8],
  MusicNote["G4", 1/2]
}]

WLJS renders music objects in an InputForm-like output, avoiding unsupported native summary boxes.
