at least two of said at least five tracks are associated with either an FX
instrument class or a vocals instrument class, and
at least two of said at least five tracks are associated with a tonal
instrument class, said tonal instrument class comprising a keyboard
instrument class, a string instrument class, a synth instrument class, a brass
instrument class, a bass instrument class, and a guitar instrument class, comprising the steps of:
(a) accessing said initial music work;
(b) if at least one track of said initial music work that is not associated with said drum instrument class is active, muting each of said at least one track associated with said drum instrument class;
(c) if at least one of said at least two tracks associated with said tonal instrument class is active, muting all of said tracks associated with said FX instrument class and said vocals instrument class;
(d) if none of said at least two tracks associated with said tonal instrument class is active:
(d1) determining an initial volume of each track associated with said FX instrument class,
(d2) determining an initial volume of each track associated with said vocals instrument class,
(d3) reducing said initial volume of each track associated with said FX instrument class to between 25% and 35% of said initial volume of said each track associated with said FX instrument class, and
(d4) reducing said initial volume of each track associated with said vocals instrument class to between 25% and 35% of said initial volume of said each track associated with said vocals instrument class;
(e) identifying a first tonal instrument class comprising:
(e1) every track associated with said synth instrument class,
(e2) every track associated with said brass instrument class, and
(e3) every track associated with said guitar instrument class;
(f) identifying a second tonal instrument class comprising:
(f1) every track associated with said string instrument class,
(f2) every track associated with said keyboard instrument class, and
(f3) every track associated with said bass instrument class;
(g) if at least two of said tracks associated with said second tonal group is active, mute any tracks associated with said first tonal instrument class;
(h) determining an initial volume of any track associated with said bass instrument class;
reducing said initial volume of any track associated with said bass instrument class to between 20% and 30% of said initial volume of said any tracks associated with said bass instrument class;
for each bar within said initial music work:
(j1) determining any active tracks within said bar,
(j2) determining an instrument class associated with each of said active tracks,
(j3) determining a number of different instrument classes associated with said active tracks in said bar,
(j4) if said number of determined instrument classes in said bar is greater than three, using a predetermined priority list to reduce said number of active instrument classes within said bar to three by muting active tracks according to said predetermined priority list;
(k) setting a volume to between 25% and 35% of an initial volume for each track not already reduced in volume, thereby forming said low energy music work from said initial music work; and
(l) performing at least a portion of said low energy music work for a user.
 
3. A method of generating a medium energy music work from an initial music work, wherein:
said initial music work comprises a plurality of bars,
and said initial music work comprises at least five tracks,
at least one of said at least five tracks is associated with a drum instrument class,
at least two of said at least five tracks are associated with either an FX instrument class or a vocals instrument class,
at least two of said at least five tracks are associated with a tonal
instrument class, said tonal instrument class comprising a keyboard
instrument class, a string instrument class, a synth instrument class, a brass
instrument class, a bass instrument class, and a guitar instrument class, comprising the steps of:
(a) accessing said initial music work;
(b) reducing a volume of every track associated with said drum instrument class by between 45% and 55%;
(c) reducing a volume of every track associated with a percussion instrument class by between 45% and 55%;
(d) if at least one of said at least two tracks associated with said tonal instrument class is active, muting all of said tracks associated with said FX instrument class and with said vocals instrument class;
(e) if none of said at least two tracks associated with said tonal instrument class is active,
(e1) determining an initial volume of each track associated with said FX instrument class,
(e2) determining an initial volume of each track associated with said vocals instrument class,
(e3) reducing said initial volume of each track associated with said FX instrument class to between 25% and 35% of said initial volume of said each track associated with said FX instrument class, and
(e4) reducing said initial volume of each track associated with said vocals instrument class to between 25% and 35% of said initial volume of said each track associated with said vocals instrument class;
reducing a volume of every track associated with said synth instrument class by between 45% and 55%;
(g) reducing a volume of every track associated with said brass instrument class by 50%;
(h) reducing a volume of every track associated with said guitar instrument class by between 45% and 55%;
reducing a volume of every track associated with said bass instrument class by between 45% and 55%;
for each bar within said initial music work:
(j1) determining any active tracks within said bar,
(j2) determining an instrument class associated with each of said active tracks,
(j3) determining a number of different instrument classes associated with said active tracks in said bar,
(j4) if said number of determined instrument classes in said bar is greater than five, using a predetermined priority list to reduce said number of active instrument classes to five by muting active tracks according to said predetermined priority list;
(k) reducing a volume to between 55% and 65% of an initial volume for each track not already having a reduction in volume applied thereto, thereby forming said medium energy music work from said initial music work; and
(l) performing at least a portion of said medium energy music work for a user.
 
5. A method of generating a high energy music work from an initial music work, said initial music work comprising at least five tracks, wherein:
said initial music work comprises a plurality of bars,
said initial music work has a master volume associated therewith, and
said initial music work comprises at least five tracks,
at least one of said at least five tracks is associated with a drum instrument class,
at least two of said at least five tracks are associated with either an FX instrument class or a vocals instrument class,
at least two of said at least five tracks are associated with a tonal instrument class, said tonal instrument class comprising a keyboard instrument class, a string instrument class, a synth instrument class, a brass instrument class, a bass instrument class, and a guitar instrument class,
and wherein is provided a database of audio loops corresponding to each of said instrument classes in said initial music work, each of said audio loops having a LUFS value associated therewith, comprising the steps of:
(a) accessing said initial music work;
(b) determining an instrument class associated with each of said at least five tracks;
(c) increasing a loudness of each of said tracks associated with said drum instrument class by a factor of between 2 and 3;
(d) if any of said at least five tracks is associated with a bass instrument class, increasing a loudness of each of said tracks associated with said bass instrument class by a factor of between 2 and 3;
(e) if any of said at least five tracks is associated with a percussion instrument class, increasing a loudness of each of said tracks associated with said percussion instrument class by a factor of between 2 and 3;
(f) for each of said at least five tracks not associated with either a percussion instrument class, a drum instrument class, or a bass instrument class,
(f1) selecting a track not associated with a percussion instrument class, a drum instrument class, or a bass instrument class,
(f2) determining a selected instrument class for said selected track,
(f3) determining a selected LUFS value for said selected track,
(f4) identifying in said database an audio loop associated with said selected instrument class having a LUFS value greater than said selected LUFS value,
(f5) replacing any audio content in said selected track with said identified audio loop;
(g) increasing said master volume of said initial music work by a factor between 150% and 250%, thereby forming said high energy work from said initial music work; and
(h) performing at least a part of said initial music work for a user.
