This program in itself will likely never produce a full melody which is perfect on its
own, the purpose of this program is to give people an idea which they can use to make
into a song.

This Program uses MidiSynth to produce piano notes.

This is an algorithm to pick a random scale and from this it chooses random notes 
to be played either in the melody portion or in the chord portion.

For the playNote and playChord methods, the first C note on the Midi Piano is at index 24 and from there on 
I have set a multiplier so that it picks a note and from the multiplier assigns the key used.

You can run the program from the Driver class.

The notes should be within the same scale
In a chord there should be at least one space between each note
A chord must consist of at least 2 notes to be considered a chord
Chords are usually played by the left hand, so the chords are always in a lower octave to the melody
It should follow the timings set out in music, such as quavers, crotchets, minims and semibreves

c# is the same as d-flat, so I have made all flat notes into the sharp of the previous note to align with my HashMap
The deep and high octaves are outliers and should not be used extensively
I use uppercase for notes within the current octave and lowercase for notes in the octave higher
    e.g. C-Scale = C, D, E, F, G, a, b, c 

To Open Command Prompt, Press the start button and search for cmd
navigate to where the project is located using **cd <folder_name>** , 
**dir** is used to check what folders are inside current directory.
Navigate to PianoAlgorithm\out\production\PianoAlgorithm
then run command **java Driver** to run the program.

The playRandom boolean variable in the Driver class 
    -> Set to true to produce a random melody
    -> Set to false if you would like the view the last melody again (melody.json)
