Ring Tones Text Transfer Language (RTTTL) is a text format that you use to create ringtones that can be uploaded to your mobile phone.

RTTTL specification.

The RTTTL code is divided into three sections that are separated by colons:
  • The name section (JingleBell)
    A string of characters represents the name of the melody.
    This can be no longer than 10 characters, and cannot contain a ":" character.

    For example: JingleBell

  • The default value section (d=8,o=5,b=112)
    Is a set of values separated by commas, where each value contains a key and a value separated by an = character, which describes the melody defaults.

    For example: d=8,o=5,b=112

    When a note is played it will have a duration of 1/8 note, as indicated by the notation d=8. Unless otherwise indicated, any note identified will be played in the fifth octave, indicated by the notation o=5. The tempo for this melody (how fast it goes) will be 112 beats per minute, as indicated by the notation b=112.

    • d - Duration (Allowed values: 1, 2, 4, 8, 16, 32)
      Duration is measured relative to other notes using a system of whole notes (1), half notes (2), quarter notes (4), eighth notes (8), sixteenth notes (16) and thirty-two notes (32). It is not measured in time (seconds or minutes).

      For example: d=8

      If d=8, the eight note is the single unit of measure, in which each eight note receives one beat.

    • o - Octave (Allowed values: 4, 5, 6, 7)
      Nokia ringtones for your mobile phone uses the following 4 four octaves (4,5,6,7):

      Octave 4 - Note A is 440Hz
      Octave 5 - Note A is 880Hz
      Octave 6 - Note A is 1760 Hz
      Octave 7 - Note A is 3520 kHz

      Piano small octaves

      For example: o=5

    • b - Beats per minute (Allowed values: 25, 28, 31, 35, 40, 45, 50, 56, 63, 70, 80, 90, 100, 112, 125, 140, 160, 180, 200, 225, 250, 285, 320, 355, 400, 450, 500, 565, 635, 715, 800 and 900.)

      If a melody is assigned a "112 beats per minute" value, this means that the melody will get one beat each (60/112 = ) 1.867 second. If you want the melody to go twice as fast, you increase the beat to 224.

      For example: b=112

    If any of the parameters is missing from the default value section, the following defaults are assumed: d=4,o=6,b=63.

  • The data section (32p,a,a,4a,...,a,4g,4c6)
    Is a set of string pairs separated by commas, where each string pair contains:
    a duration-pitch-octave and optional dotting (which increases the duration of the note by one half).

    For example:

    • Duration (Allowed values are: 1,2,4,8,16,32)
      See explanation above.

    • Pitch (Allowed values are: a, a#, b, h, c, c#, d, d#, e, f, f#, g, g#, p)
      The pitch represents a note or a rest.
      The following pitch values (lower or upper case) are allowed:

      Pitch Represents note
      a A
      a# A# or Bb
      b or h B or Cb

      In the USA the C major scale is written as: C,D,E,F,G,A,B,C. In Europe (at least in Estonia) the C major scale is written as: C,D,E,F,G,A,H,C.
      c C
      c# C# or Db
      d D
      d# D# or Eb
      e E or Fb
      f F or E#
      f# F# or Gb
      g G
      g# G# or Ab
      p Rest or pause

    • Octave (Allowed values are: 4, 5, 6, 7)
      See explanation above.

    • Optional dotting (Allowed value: .)
      A dotted character (.) can be specified AFTER the duration-pitch-octave pair.
      A dotted duration is one in which a note is given the duration of "itself + half of itself."

      For example:
      A dotted quarter note C, octave 6 (4c6.) has a value of a quarter note plus an eighth note.

      A dotted eighth note F#, octave 5 (8f#5.), has a duration value of an eighth note plus a sixteenth note.

      A dotted whole note D, octave 7 (1D7.), has a duration value of a whole note plus a half note.

    Examples (d=4,o=6,b=63):
    • If no duration or octave specifier are present, the default applies.
    • The character p indicates a rest (pause). Because rests don't occur in an octave, you don't use an octave indicator.

    [duration]-pitch-[octave][dotting] pair Explanation
    8f#5 1/8 note F#, octave 5
    8d5 1/8 note D, octave 5
    8p 1/8 pause
    1p 1 pause
    4p 1/4 pause
    4p. 1/4 + 1/8 pause
    p default length 1/4 pause
    c5 default length 1/4, note C, octave 5
    8d 1/8 note D, default octave 6
    2e. 1/2 + 1/4 note E, default octave 6
    4c5. 1/4 + 1/8 note C, octave 5
    8d#6. 1/8 + 1/16 note D#, octave 6
    c# default length 1/4, note C, default octave 6
    d default length 1/4, note D, default octave 6
