RTTTL

RTTTL specification.

• 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
    
    
    
    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:
  32p,8g.,16e,c,e,g,2c6,8e6,16d6,c6,e,f#,2g,g,e6,8d6,c6,2b,8a.,16b,c6,c6,g,e,c
  
  
  • 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.
