Harmony

MMA can generate harmony notes for you ... just like hitting two or more keys on the piano! And you don't have to take lessons.

Automatic harmonies are available for the following track types: Bass, Walk, Arpeggio, Scale, Solo and Melody.

Just in case you are thinking that MMA is a wonderful musical creator when it comes to harmonies, don't be fooled. MMA 's ideas of harmony are quite facile. It determines harmony notes by finding a note lower or higher than the current note being sounded within the current chord. And its notion of ``open'' is certainly not that of traditional music theory. But, the sound isn't too bad.

Harmony

To enable harmony notes, use a command like:

Solo Harmony 2

You can set a different harmony method for each bar in your sequence.

The following are valid harmony methods:

  2 or 2Below
    Two part harmony. The harmony note selected is lower (on the scale).

  28Below
    Two part harmony, the harmony note is lowered by an additional octave.

  2Above
    The same as ``2'', but the harmony note is raised an octave.

  28Above
    The same as ``2Above'', but the harmony note is raised by two octaves.

  3 or 3Below
    Three part harmony. The harmony notes selected are lower.

  3Above
    The same as ``3'', but both notes are raised an octave.

  38Above
    Same as ``3'', but the two harmony notes are raised by two octaves.

  38Below
    Same as ``3'', but the two harmomy notes are lowered by two octaves.

  Open or OpenBelow
    Two part harmony, however the gap between the two notes is larger than in ``2''.

  Open8Below
    Same as ``OpenBelow'', but the harmony note is lowered by an additional octave.

  OpenAbove
    Same as ``Open'', but the added note is above the original.

  Open8Above
    Same as ``OpenAbove'', but the added note is raised by an additional octave.

  8 or 8Below
    A note 1 octave lower is added.

  8Above
    A note 2 octave higher is added.

  16 or 16Below
    A single note two octaves below is added.

  16Above
    A single note two octaves above are added.

  24 or 24Below
    A single note three octaves below is added.

  24Above
    A single note three octaves above is added.

You can combine any of the above harmony modes by using a ``+''. For example:

  OPEN+8Below
    will produce harmony notes with an ``Open'' harmony and a note an octave below the current note.

  3Above+16
    will generate 2 harmony notes above the current note plus a note 2 octaves below.

  8Below+8Above+16Below
    will generate 3 notes: one 2 octaves below the current, one an octave below, and one an octave above.

There is no limit to the number of modes you can concatenate. Any duplicate notes generated will be ignored.

All harmonies are created using the current chord.

To disable harmony use a ``0'', ``-'' or ``None''.

Be careful in using harmonies. They can make your song sound heavy, especially with BASS notes (applying a different volume may help).

The command has no effect in DRUM or CHORD tracks.

#
HarmonyOnly

As a added feature to the automatic harmony generation discussed in the previous section, it is possible to set a track so that it only plays the harmony notes. For example, you might want to set up two arpeggio tracks with one playing quarter notes on a piano and a harmony track playing half notes on a violin. The following snippet is extracted from the song file ``Cry Me A River'' and sets up 2 different choir voices:

Begin Arpeggio Sequence A4 Voice ChoirAahs Invert 0 1 2 3 SeqRnd Octave 5 RSkip 40 Volume p Articulate 99 End Begin Arpeggio-2 Sequence A4 Voice VoiceOohs Octave 5 RSkip 40 Volume p Articulate 99 HarmonyOnly Open End

Just like the HARMONY command, above, you can have different settings for each bar in your sequence. Setting a bar (or the entire sequence) to ``-'', ``None'' or ``0'' disables the HARMONYONLY settings.

The command has no effect in DRUM or CHORD tracks.

If you want to use this feature with SOLO or MELODY tracks you can duplicate the notes in your RIFF or in-line notation or with the AUTOHARMONYTRACKS COMMAND.

#
HarmonyVolume

By default, MMA will use a volume (velocity) of 80% of that used by the original note for all harmony notes it generates. You can change this with the the HARMONYVOLUME command. For example:

Begin Solo Voice JazzGuitar Harmony Open HarmonyVolume 80 End

You can specify different values for each bar in the sequence. The values are percentages and must be greater than 0 (large values work just fine if you want the harmony louder than the original). The command has no effect in DRUM or PLECTRUM tracks.
