Musical Substitution Cipher

Description:

This Python program takes a text input from the user and generates an XML file where each letter in the input text is associated with a specific musical pitch. The pitches start at C3 for the letter 'A' and proceed chromatically through the musical scale.

Luis = B3 G#4 G#3 F#4

Run the code

Python Code

import xml.etree.ElementTree as ET

# Mapping letters to pitches

def letter_to_pitch(letter):

pitch_dict = {

'A': 'C3', 'B': 'C#3', 'C': 'D3', 'D': 'D#3', 'E': 'E3', 'F': 'F3', 'G': 'F#3',

'H': 'G3', 'I': 'G#3', 'J': 'A3', 'K': 'A#3', 'L': 'B3', 'M': 'C4', 'N': 'C#4',

'O': 'D4', 'P': 'D#4', 'Q': 'E4', 'R': 'F4', 'S': 'F#4', 'T': 'G4', 'U': 'G#4',

'V': 'A4', 'W': 'A#4', 'X': 'B4', 'Y': 'C5', 'Z': 'C#5'

}

return pitch_dict.get(letter.upper(), 'rest')

# Create XML structure

# Get user input and create XML file
