copied!<p>I add lots of comments; everywhere. I took the time to write out what logic is happening in human-readable form for every single line of my 500 line music-generation algorithm, and it saved me so much time, and my other friends who were helping.</p> <p>Here's what I did (as a start):</p> <pre><code>def __init__(self): self.chromatic = ['C', ['C#', 'Db'], 'D', ['D#', 'Eb'], 'E', 'F', ['F#', 'Gb'], 'G', ['G#', 'Ab'], 'A', ['A#', 'Bb'], 'B'] self.steps = {} self.steps['major'] = [2, 2, 1, 2, 2, 2, 1] self.steps['natural minor'] = [2, 1, 2, 2, 1, 2, 2] self.steps['harmonic minor'] = [2, 1, 2, 2, 1, 3] self.steps['melodic minor up'] = [2, 1, 2, 2, 2, 2, 1] self.steps['melodic minor down'] = [2, 2, 1, 2, 2, 1, 2] self.steps['dorian'] = [2, 1, 2, 2, 2, 1, 2] self.steps['mixolydian'] = [2, 2, 1, 2, 2, 1, 2] self.steps['ahava raba'] = [1, 3, 1, 2, 1, 2, 2] self.steps['minor penatonic blues'] = [3, 2, 2, 3, 2] self.list = [] def scale(self, note, name): # Function to generate a scale from the required base note. if re.sub('[^0-9]', '', note) == '': # Checks for nonexistent octave number octave = 5 # Defaults to 5 else: # If octave number exists octave = int(re.sub('[^0-9]', '', note)) # Extracts octave number from note note = re.sub('[0-9]', '', note) # Strips all numbers from note scale = [] # Initializes the scale to be empty for i in rlen(self.chromatic): # Loops through all elements of the Chromatic scale if self.chromatic[i] is not list: # If the note is just a natural if note == self.chromatic[i]: scale = [i + 1] # Check if the note is in the chromatic. If it is, add it. else: if note in self.chromatic[i]: scale = [i + 1] # If the note is in a key of the chromatic, add it too. It is a sharp/flat. for i in rlen(self.steps[name]): # Loops through desired scale scale.append(self.steps[name][i] + scale[i]) # Adds string notes following the algorithm of the scale scale[i + 1] = scale[i + 1] % len(self.chromatic) # Modulo length of Chromatic scale </code></pre> <p>It's a start (and an example with cruddy code), but it helps me debug code <em>really</em> quickly.</p>
