🎵 Music Interval Trainer

A command-line ear training tool for practicing musical intervals. It plays ascending, descending, or harmonic intervals and quizzes you based on lesson presets.

For listening only — no looking required. Interval names are spoken aloud after each playback.

🎹 Features

• Supports different interval types (consonance, dissonance, etc.)
• Customizable playback formats: harmonic, melodic ascending/descending, mixed
• Spoken interval names using espeak
• Lesson selection via command-line
• Runs offline using a virtual environment

---

🧰 Requirements

• Python 3.7+
• espeak (for speech output, automatically installed in setup.sh script)
• fluidsynth (for audio output, may not be necessary, automatically installed in setup.sh script)
• Linux (Debian-based recommended) or WSL on Windows

Install espeak on Debian/Ubuntu (or let the setup.sh script install it for you):

sudo apt install espeak

---

🚀 Setup

1. Clone or download this repository.

2. Allow execution permission for setup.sh and run.sh (sudo chmod +x setup.sh run.sh).

3. Run the setup script (installs dependencies):

   ./setup.sh

   This will create a virtual environment and install required Python packages.

4. Start a lesson. For example, run:

   ./run.sh 1

🧠 Usage

To show all available lessons, run:

./run.sh -l

To start lesson x (replace x with a number), run:

./run.sh x

To change the instrument to e.g. violin, run :

./run.sh 1 -i violin

To show all available options, run:

./run.sh --help

If you want to use the raw python script instead of running run.sh, do the same with main.py:

python3 main.py <lesson_number> [-i INSTRUMENT]

Arguments:

• <lesson_number>: Choose a lesson (1–4)
• -i, --instrument: SCAMP instrument to use (default: piano)
• -l, --list: List available lessons
• -p, --loop: Loop the lesson to infinity, gotta practice more
