How to use it:
- Select a Root Note: Choose the starting note of your scale (e.g., C, G, F#).

- Click “Show Scale”: The output will display all the notes in your chosen scale.
- Click “Play Scale”: Hear the scale played back to train your ear and understand its unique sound.
2. The Chord Builder

How to use it:
- Select a Root Note: Choose the foundational note of your chord.
- Choose a Chord Type: Select the chord’s quality, such as Major (M), minor (m), 7th, or diminished (dim).

How to use it:
- Select a Key: Choose the musical key you are working in.
- Choose a Cadence Type: Select from the most common types:
- Authentic (V-I): The strongest, most final-sounding cadence.
- Plagal (IV-I): The “Amen” cadence, also sounds final but softer.
- Half (I-V): An unresolved, questioning cadence that leaves the listener wanting more.
- Deceptive (V-vi): A surprise resolution that avoids the expected tonic chord.
- Click “Show Cadence” & “Play Cadence”: See and hear how these fundamental harmonic progressions work in practice.
