Instance Method Details

#un_unicode_accdtls(str_note) ⇒ Object

Turns all Unicode musical characters in str_note to their ASCII equivalent, and returns the result.

Note: the function is intended for viewing musical scales through deficient browsers like IE 6 and 7. Characters may appear as blocks in these environments.
