SECEA-5, or Secondhand EnCoded English Alphabet 5, is a code of English that some people use, as well as SECEA-7, and SECEA-9. There's also an SECEA-98 alphabet, which is the highest it officially goes, which covers capital letters and lowercase letters, as well as text formatting (bolds, italics, strikethroughs), and numbers, as well as a few symbols and accents!
The SECEA is typically used with Wintergarten, but can also be used with Harpsichord and Grand Piano. SECJK (Japanese Katakana) is used with Kojo and Flute, SECJH (Hiragana) is used with Violin and SECIA 235 (India) uses Pizzicato and Styrofoam tubes :D
Just so you know, "Music Box of Terror" on YouTube also uses this code sometimes! :D
