Ring Tone Text Transfer Language
Ring Tone Text Transfer Language (RTTTL) was developed by Nokia to be used to transfer ringtones to cellphone by Nokia. The RTTTL format is a string divided into three sections: name, default value, and data. The "jintu" section consists of a string describing the name of the ringtone. It can be no longer than 10 characters, and cannot contain a colon ":" character. (However, since the Smart Messaging specification allows names up to 15 characters in length, some applications processing RTTTL also do so.) The "default value" section is a set of values separated by  commas, where each value contains a key and a value separated by an "=" character, which describes certain defaults which should be adhered to during the execution of the ringtone. Possible names are The "data" section consists of a set of character strings separated by commas, where each string contains a "duration", "pitch", "octave" and optional "dotting" (which increases the duration of the note by one half). The format of RTTTL notation is similar to the Music Macro Language found in BASIC implementations present on many early microcomputers. Technical specification. To be recognized by ringtone programs, an RTTTL/Nokring format  ringtone must contain three specific elements: name, settings, and notes. For example, here is the RTTTL ringtone for Haunted House: codice_1 The three parts are separated by a colon. Durations. Standard musical durations are denoted by the following notations: Dotted rhythm patterns can be formed by appending a period (".") character to the end of a duration/beat/octave element. Octave. The RTTTL format allows octaves starting from the A below middle C and going up four octaves. This corresponds with the inability of cellphones to reproduce certain tones audibly. These octaves are numbered from lowest pitch to highest pitch from  4 to 7. The octave should be left out of the notation in the case of a rest or pause in the pattern. Example. An example of the RTTTL format would be
