Music Flat Sign ♭

The Music Flat Sign character (♭) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference ♭, the decimal numeric character reference ♭, or the hexadecimal numeric reference ♭. The character is assigned Unicode code point U+266D in the Universal Character Set.

The flat sign (♭) is a musical notation symbol that lowers a note by one semitone. It is essential in music theory, chord notation, and key signature descriptions. The flat symbol is one of three accidental marks in Western music notation, alongside the sharp (♯) and natural (♮).

Symbol entities encompass a wide variety of special characters used in legal disclaimers, intellectual property notices, typographic ornaments, card suit indicators, and miscellaneous notation throughout web content. These characters appear in website footers for copyright notices, product pages for trademark symbols, academic papers for dagger footnote markers, and decorative or gaming contexts for card suits and stars.

When deciding how to encode the Music Flat Sign character in your HTML documents, the named entity ♭ is generally the most readable choice for developers reviewing or maintaining source code. The decimal form ♭ and hexadecimal form ♭ are equally valid alternatives that work in contexts where named entities may not be supported, or when generating HTML output programmatically from server-side code. All three representations produce identical visual output in every modern web browser.

Use the flat sign in music theory content, chord notation (B♭, E♭), key signature descriptions, and educational music content. It is essential for any web content about music theory where accidentals need to be displayed inline with text rather than in sheet music notation.
