Harmony
</H1>
<P>
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> can generate harmony notes for you ... just like hitting two
or more keys on the piano! And you don't have to take lessons.
<P>
Automatic harmonies are available for the following track types: Bass,
Walk, Arpeggio, Scale, Solo and Melody.
<P>
Just in case you are thinking that
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> is a wonderful musical
creator when it comes to harmonies, don't be fooled.
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> '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.
<P>
<H1><A NAME="SECTION001510000000000000000"></A> <A NAME="harmony"></A>
<BR>
Harmony
</H1>
<P>
To enable harmony notes, use a command like:
<P>
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
<tr><td>
<B>Solo Harmony 2 </B>
</td></tr>
</Table>
<P>
You can set a different harmony method for each bar in your sequence.
<P>
The following are valid harmony methods:
<P>
<DL COMPACT>
<DT></DT>
<DD><DL>
<DT><STRONG>2 or 2Below</STRONG></DT>
<DD>Two part harmony. The harmony note
selected is lower (on the scale).
<P>
</DD>
<DT><STRONG>28Below</STRONG></DT>
<DD>Two part harmony, the harmony note is lowered by an
additional octave.
<P>
</DD>
<DT><STRONG>2Above</STRONG></DT>
<DD>The same as ``2'', but the harmony note is raised an
octave.
<P>
</DD>
<DT><STRONG>28Above</STRONG></DT>
<DD>The same as ``2Above'', but the harmony note is raised by
two octaves.
<P>
</DD>
<DT><STRONG>3 or 3Below</STRONG></DT>
<DD>Three part harmony. The harmony notes
selected are lower.
<P>
</DD>
<DT><STRONG>3Above</STRONG></DT>
<DD>The same as ``3'', but both notes are raised an
octave.
<P>
</DD>
<DT><STRONG>38Above</STRONG></DT>
<DD>Same as ``3'', but the two harmony notes are raised
by two octaves.
<P>
</DD>
<DT><STRONG>38Below</STRONG></DT>
<DD>Same as ``3'', but the two harmomy notes are lowered
by two octaves.
<P>
</DD>
<DT><STRONG>Open or OpenBelow</STRONG></DT>
<DD>Two part harmony, however the gap
between the two notes is larger than in ``2''.
<P>
</DD>
<DT><STRONG>Open8Below</STRONG></DT>
<DD>Same as ``OpenBelow'', but the harmony note is lowered by
an additional octave.
<P>
</DD>
<DT><STRONG>OpenAbove</STRONG></DT>
<DD>Same as ``Open'', but the added note is above the
original.
<P>
</DD>
<DT><STRONG>Open8Above</STRONG></DT>
<DD>Same as ``OpenAbove'', but the added note is
raised by an additional octave.
<P>
</DD>
<DT><STRONG>8 or 8Below</STRONG></DT>
<DD>A note 1 octave lower is added.
<P>
</DD>
<DT><STRONG>8Above</STRONG></DT>
<DD>A note 2 octave higher is added.
<P>
</DD>
<DT><STRONG>16 or 16Below</STRONG></DT>
<DD>A single note two octaves below is
added.
<P>
</DD>
<DT><STRONG>16Above</STRONG></DT>
<DD>A single note two octaves above are added.
<P>
</DD>
<DT><STRONG>24 or 24Below</STRONG></DT>
<DD>A single note three octaves below is
added.
<P>
</DD>
<DT><STRONG>24Above</STRONG></DT>
<DD>A single note three octaves above is added.
<P>
</DD>
</DL>
</DD>
</DL>
<P>
You can combine any of the above harmony modes by using a ``+''. For
example:
<P>
<DL COMPACT>
<DT></DT>
<DD><DL>
<DT><STRONG>OPEN+8Below</STRONG></DT>
<DD>will produce harmony notes with an ``Open''
harmony and a note an octave below the current note.
<P>
</DD>
<DT><STRONG>3Above+16</STRONG></DT>
<DD>will generate 2 harmony notes above the current
note plus a note 2 octaves below.
<P>
</DD>
<DT><STRONG>8Below+8Above+16Below</STRONG></DT>
<DD>will generate 3 notes: one 2 octaves
below the current, one an octave below, and one an octave above.
<P>
</DD>
</DL>
</DD>
</DL>
<P>
There is no limit to the number of modes you can concatenate. Any
duplicate notes generated will be ignored.
<P>
All harmonies are created using the current chord.
<P>
To disable harmony use a ``0'', ``-'' or ``None''.
<P>
Be careful in using harmonies. They can make your song sound heavy,
especially with B<SMALL>ASS</SMALL> notes (applying a different volume may
help).
<P>
The command has no effect in D<SMALL>RUM</SMALL> or C<SMALL>HORD</SMALL> tracks.
<P>
<H1><A NAME="SECTION001520000000000000000"></A> <A NAME="harmonyonly"></A>
<BR>
HarmonyOnly
</H1>
<P>
As a added feature to the automatic harmony generation discussed in
the previous section, it is possible to set a track so that it
<SPAN CLASS="textit">only</SPAN> 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:
<P>
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
<tr><td>
<B>Begin Arpeggio
<BR> Sequence A4
<BR> Voice ChoirAahs
<BR> Invert 0 1 2 3
<BR> SeqRnd
<BR> Octave 5
<BR> RSkip 40
<BR> Volume p
<BR> Articulate 99
<BR>
End
<BR>
<BR>
Begin Arpeggio-2
<BR> Sequence A4
<BR> Voice VoiceOohs
<BR> Octave 5
<BR> RSkip 40
<BR> Volume p
<BR> Articulate 99
<BR> HarmonyOnly Open
<BR>
End </B>
</td></tr>
</Table>
<P>
Just like the H<SMALL>ARMONY</SMALL> 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 H<SMALL>ARMONY</SMALL>O<SMALL>NLY</SMALL> settings.
<P>
The command has no effect in D<SMALL>RUM</SMALL> or C<SMALL>HORD</SMALL> tracks.
<P>
If you want to use this feature with S<SMALL>OLO</SMALL> or M<SMALL>ELODY</SMALL>
tracks you can duplicate the notes in your R<SMALL>IFF</SMALL> or in-line
notation <SPAN CLASS="textit">or</SPAN> with the <A HREF="node10.html#autosolotracks">A<SMALL>UTO</SMALL>H<SMALL>ARMONY</SMALL>T<SMALL>RACKS
COMMAND</SMALL></A>.
<P>
<H1><A NAME="SECTION001530000000000000000"></A> <A NAME="harmonyvolume"></A>
<BR>
HarmonyVolume
</H1>
<P>
By default,
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> 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 H<SMALL>ARMONY</SMALL>V<SMALL>OLUME</SMALL> command. For example:
<P>
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
<tr><td>
<B>Begin Solo
<BR> Voice JazzGuitar
<BR> Harmony Open
<BR> HarmonyVolume 80
<BR>
End </B>
</td></tr>
</Table>
<P>
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 D<SMALL>RUM</SMALL> or P<SMALL>LECTRUM</SMALL> tracks.
