1 /* 2 * This program interprets melodic lines given in ABC notation as a chromesthete might. 3 * 4 * A Pitch class will be defined, and will take center stage in the processing. 5 * 6 * Interpreting a melody in ABC notation will amount to flashing colored rectangles for prescribed durations,while sounding the pitch! The color of the rectangle will correspond to pitch class. 7 * The duration will correspond to the duration of the note. 8 * 9 * The duration will be held constant at 1 beat. 10 * 11 * These sorts of images will appear on the screen, the chromesthetic output box, a text input box, and an error message box. Simplicity of design is rendered by permitting only one box 12 * to be on the screen at a time. 13 * 14 * ABC notes represent these examples: 15 * C, D, E, C D E c d e 16 * 17 * Google ABC music representation if you need help. 18 * 19 * By Hunter Gersitz | SUNY Oswego Fall 2019 20 * */ 21 22 package chromesthesia1; 23 24 import painter.SPainter; 25 26 import javax.swing.*; 27 import java.util.Scanner; 28 29 public class chromesthesia { 30 31 // INFRASTRUCTURE FOR THE PROBLEM -- LAUNCHING A "GRAPHICS" THREAD 32 33 public static void main(String[] args) { 34 SwingUtilities.invokeLater(new ThreadForGUI()); 35 } 36 37 private static class ThreadForGUI implements Runnable { 38 public void run() { 39 new chromesthesia(); 40 } 41 } 42 43 private chromesthesia() { 44 interpreter(); 45 } 46 47 // FEATURED VARIABLES 48 49 private static SPainter miro; 50 private static Pitch[] pitches; 51 52 // THE INTERPRETER 53 54 private static void interpreter() { 55 56 initialization(); //miro and pitches 57 58 while (true) { 59 String input = getInput(); 60 61 if (input.equalsIgnoreCase("EXIT")) { 62 break; 63 } else { 64 try { 65 playMelody(input, pitches); 66 } catch (Exception ex) { 67 showErrorMessage(ex.toString()); 68 } 69 } 70 } 71 cleanup(); //miro has to go 72 73 } 74 75 // METHODS FEATURING TO THE CHROMESTHETIC PITCHES 76 77 private static Pitch[] establishPitches(SPainter painter) { 78 Pitch[] pitches = new Pitch[21]; 79 Pitch pitchMiddleC = new Pitch("C", painter); 80 pitches[0] = pitchMiddleC; 81 Pitch pitchLowC = new Pitch("C,", painter); 82 pitches[1] = pitchLowC; 83 Pitch pitchHighC = new Pitch("c", painter); 84 pitches[2] = pitchHighC; 85 Pitch pitchMiddleD = new Pitch("D", painter); 86 pitches[3] = pitchMiddleD; 87 Pitch pitchLowD = new Pitch("D,", painter); 88 pitches[4] = pitchLowD; 89 Pitch pitchHighD = new Pitch("d", painter); 90 pitches[5] = pitchHighD; 91 Pitch pitchMiddleE = new Pitch("E", painter); 92 pitches[6] = pitchMiddleE; 93 Pitch pitchLowE = new Pitch("E,", painter); 94 pitches[7] = pitchLowE; 95 Pitch pitchHighE = new Pitch("e", painter); 96 pitches[8] = pitchHighE; 97 98 // notes F and f 99 Pitch pitchMiddleF = new Pitch("F", painter); 100 pitches[9] = pitchMiddleF; 101 102 Pitch pitchLowF = new Pitch("F,", painter); 103 pitches[10] = pitchLowF; 104 105 Pitch pitchHighF = new Pitch("f", painter); 106 pitches[11] = pitchHighF; 107 108 // notes G and g 109 Pitch pitchMiddleG = new Pitch("G",painter); 110 pitches[12] = pitchMiddleG; 111 112 Pitch pitchLowG = new Pitch("G,",painter); 113 pitches[13] = pitchLowG; 114 115 Pitch pitchHighG = new Pitch("g",painter); 116 pitches[14] = pitchHighG; 117 118 // NOTES A and a 119 Pitch pitchMiddleA = new Pitch("A",painter); 120 pitches[15] = pitchMiddleA; 121 122 Pitch pitchLowA = new Pitch("A,",painter); 123 pitches[16] = pitchLowA; 124 125 Pitch pitchHighA = new Pitch("a",painter); 126 pitches[17] = pitchHighA; 127 128 // NOTES B and b 129 Pitch pitchMiddleB = new Pitch("B",painter); 130 pitches[18] = pitchMiddleB; 131 132 Pitch pitchLowB = new Pitch("B,",painter); 133 pitches[19] = pitchLowB; 134 135 Pitch pitchHighB = new Pitch("b",painter); 136 pitches[20] = pitchHighB; 137 138 139 return pitches; 140 } 141 142 private static Pitch find(String token, Pitch[] pitches) throws Exception { 143 for (Pitch pitch : pitches) { 144 if (pitch.abcName().equals(token)) { 145 return pitch; 146 } 147 } 148 throw new Exception("### PITCH " + token + " NOT FOUND"); 149 } 150 151 private static void display(Pitch[] pitches) { 152 for (Pitch pitch : pitches) { 153 System.out.println(pitch.toString()); 154 } 155 } 156 157 private static void playMelody(String input, Pitch[] pitches) throws Exception { 158 Scanner scanner = new Scanner(input); 159 while (scanner.hasNext()) { 160 String token = scanner.next(); 161 Pitch pitch = find(token, pitches); 162 pitch.play("1"); 163 } 164 } 165 166 // INITIALIZATION, CLEANUP, GETTING INPUT, ERROR MESSAGING 167 168 static private void showErrorMessage(String message) { 169 miro.setVisible(false); 170 JOptionPane.showMessageDialog(null, message); 171 } 172 173 private static void initialization() { 174 // ESTABLISH THE PAINTER AND GIVE IT A SUBSTANTIAL BRUSH WIDTH 175 miro = new SPainter("Chromesthesia 1", 500, 500); 176 miro.setVisible(false); 177 miro.setBrushWidth(7); 178 // ESTABLISH PITCH CLASS OBJECTS 179 pitches = establishPitches(miro); 180 display(pitches); 181 } 182 183 private static String getInput() { 184 miro.setVisible(false); 185 String label = "Please enter a melody in ABC notation, or EXIT ....
