This Python code generates sine waves and plays the pentatonic scale using the pyaudio library.
- Python 3.x
pyaudiolibrary
- Clone or download the code from the repository.
- Install portaudio, a dependency of pyaudio using the the following command:
brew install portaudio
- Install the required
pyaudiolibrary using the following command:
pip install pyaudio
- Run the Python script
sine_wave_pentatonic_scale.py. - The script will generate sine waves for each note in the pentatonic scale and play them.
- The duration of each note is set to 1 second.
- Make sure your computer's audio output is configured correctly to hear the generated sound.
import numpy as np
import pyaudio
# Set up the audio stream
p = pyaudio.PyAudio()
stream = p.open(format=pyaudio.paFloat32,
channels=1,
rate=44100,
output=True)
# Define the pentatonic scale frequencies
pentatonic_scale = [261.63, 293.66, 329.63, 392.00, 440.00, 523.25]
# Generate and play the sine waves
for freq in pentatonic_scale:
duration = 1.0 # Duration in seconds
t = np.linspace(0, duration, int(duration * 44100), False)
samples = np.sin(2 * np.pi * freq * t)
stream.write(samples.astype(np.float32).tobytes())
# Clean up the audio stream and terminate PyAudio
stream.stop_stream()
stream.close()
p.terminate()
