FONTLOG for the Bravura font
============================

This file provides detailed information on the Bravura Font Software. This information should be distributed along with the Bravura fonts and any derivative works.

The Bravura Font Software is a family consisting of two fonts, Bravura and Bravura Text.


Basic font information
----------------------
Bravura is a Unicode typeface designed by Steinberg for its in-development music notation and scoring application.

It is compliant with version 1.0 of the Standard Music Font Layout (SMuFL), a community-driven standard for how music symbols should be laid out in the Unicode Private Use Area (PUA) in the Basic Multilingual Plane (BMP) for compatibility between different scoring applications.

More information about Steinberg's scoring application can be found at:

http://www.steinberg.net/

More information about SMuFL can be found at:

http://www.smufl.org/


Note for developers
-------------------
If you are intending to use Bravura as part of your own software application, please refer to the 'Notes for implementers' section in the SMuFL specification for useful information about Bravura's metrics and how glyphs are registered.
