- - - - Audio Pitch Recognition
        
        Microphone Input
        
        Automatic Input Device Configuration
        
        Audio Analysis Script (for notes)
        
        Pitch Identifier Module
        
        float freq
        
        Determined by measuring the peaks / strongest signals on a spectrogram-style analysis of the audio input
        
        int pitch
        
        Determined by running the frequency through the derived equation n = (12log(f/27.5))/log2, where n is the number of semitones above A1 and f is the frequency detected. n will not come out as an integer due to very slight inaccuracies in tuning and microphone input. so it will be rounded
        
        An external mathematics library will probably need to be linked in order to run the required logarithmic calculations
      - Visual Pitch Recognition
        
        Camera Input
        
        Automatic Input Device Configuration
        
        Movement Tracking (for fingers)
        
        Identification of Changing Pixels in a set Resolution
        
        array screenPos: On-Screen Position
        
        Rate of Change
        
        array relativePos: Relative Position on Keyboard
  - - - Visuals Generator
        
        MIDI File Decoder
        
        array noteAttributes
        
        Note Object Creator
        
        float speed
        
        float length
        
        int time
        
        array position
        
        int pitch
        
        Monitor Configuration
        
        Resolution

        Keyboard Position Detection
        
        Camera Placed Above Piano - Top Down View
        
        User can then rotate image until the keyboard is perfectly horizontal on-screen
        
        User clicks on middle C (C4), C3 and C5 to mark their position (camera overlay active at this point)
        
        Script to configure coordinates of each note's target
  - - - Average and Boundary Delay Display
        
        analysis of the note object log
        
        float getMeanDelay(), int getUpperDelay() and
        int getLowerDelay(): return the mean, lowest, and highest "delay" attribute of all entries in the note object log
        
        Monitor Configuration
        
        Resolution
        
        Refresh Rate
      - "Most Missed Note" Display
        
        analysis of the note object log
        
        int getMostMissed(): return the pitch that the user failed to play the most times by analysing every note's "pitch" attribute and finding the mode
      - Storing each note object's final attributes in a log (for each individual song playthrough)
        
        time
        
        int
        
        the time that the note should be pressed, since the start of the song, in ms
        
        missed
        
        bool
        
        whether the user failed to play the note or not
        
        delay
        
        int
        
        the time that the note was pressed, since the start of the song, in ms
        
        pitch
        
        int
        
        the number of semitones above A1 that the note sounds
      - Accuracy & Rank Display
        
        analysis of the note object log
        
        float getScore() and string getRank(): calculate and return percentage of the notes that weren't missed using the "missed" attribute, and using a set of constant boundaries, a rank from F to S+
