Scales & microtonality
----------------------

- :doc:`Scales <pitch_scales_microtonality_scale_example>` — Demo of the scamp_extensions Scale object, a highly flexible representation of a scale that can be indexed into infinitely in both directions from a root note. *(needs scamp_extensions)*
- :doc:`Microtonal Playback and Notation <tutorial_18_microtonal>` — Plays a few microtonal chords and notates them, turning on exact microtonal annotations.


Pitch spelling
--------------

- :doc:`Pitch Spelling <tutorial_21_pitch_spelling>` — Demonstrates the ability to define note pitch spelling using the optional properties argument to "play_note".
- :doc:`Voice Leading / spelling policy <pitch_pitch_spelling_voice_leading>` — Rule-based four-part voice leading over a scale, spelled in E major via the `default_spelling_policy` argument. *(needs scamp_extensions)*


Glissando
---------

- :doc:`Glissando from Envelope <tutorial_14_gliss_from_envelope>` — Plays a glissando by passing an Envelope to the pitch parameter of play_note.
- :doc:`Envelope Shorthand <tutorial_15_envelope_shorthand>` — Plays two glissandi by passing lists instead of envelopes to the pitch argument of play_note.
