Synthesizing tones to generate music

The previous section described how to generate a simple monotone, but it's not very meaningful. It was just a single frequency through the signal. Let's use that principle to synthesize music by stitching different tones together. We will be using standard tones such as A, C, G, and F to generate music. In order to see the frequency mapping for these standard tones, check out this link:

Let's use this information to generate a musical signal.

Create a new Python file and import the following packages:

import json
import numpy as np
import matplotlib.pyplot as plt
from import write

Define a function to generate a tone based on the input parameters:

# Synthesize the tone based on the input parameters
def tone_synthesizer(freq, duration, amplitude=1.0, sampling_freq=44100):
    # Construct the time axis
    time_axis = np.linspace(0, duration...
