   In order to be able to generate sheet music
   1. pip install music21 
   2. pip install matplotlib
   3. Install Musescore https://musescore.org/en/download
   4. Open sheet_music_generation/music21_musescore_work_together_configurer.py in text editor
   5. Change the path to the installed location of Musescore
   6. run: python sheet_music_generation/music21_musescore_work_together_configurer.py

You are all set !!

degree of randomness in the generated music
should be in the range [0.1 to 2]

number of bars to seed with while generating the music 
(how much of actual music to feed to generate new music)

number of notes that can be played together at the same time
it may not be exact because chord progression is not bound by it
but it effects the melody produced
its value should be in the range [1 to 5]
I suggest the front-end to have a slider rather than exact number as a input

If the produced music has too many notes at a same time
you can decrease this value
This attribute is optional
if not provided it takes the default value of 4

can take values: "higher" or "lower"
it modifies the music to be in higher or lower octave
higher octave means of high pitch and lower means of lower pitch

this number specifies how many octaves higher or lower to go
if key is D#, octave_type is "higher" and which_octave is 2
then the music will shift towards higher frequency, 2 octave higher in the D# key 
if octave_type == "lower" then which_octave can be in the range [0 to 2]
if octave_type == "higher" then which_octave can be in the range [0 to 3]

"num_bars"
"BPM"
"chord_temperature"
"seed_length"

following parameters can come independently
"genre_id"
"instrument_id"
"note_cap"

following paramaters must come together
"key"
"octave_type"
"which_octave"

{
    "key": "F#", 
    "octave_type": "higher",

eg:
 localhost:5000/api/v1/sheet_music/pdf
 returns sheet music as a pdf file
 
 localhost:5000/api/v1/sheet_music/png
 returns sheet music as a png image

eg:
 localhost:5000/api/v1/music_mp3
 
 returns the music in mp3 format
