Lesson library
31 short theory lessons you can do right inside the Sketchpad. Open a card and the lesson docks beside your work — it sets up the level and key it needs, and stays visible while you build. Star ★ the ones you want to come back to.
Step 1 · Choose your level and key
Pick the level that matches you today. You can change it any time — nothing is lost.
Choose a key
The key is the musical “home base” of your song. Major keys usually sound brighter; minor keys usually sound darker or more emotional.
Project settings (whole song)
Tempo and time signature apply to the whole project.
Step 2 · Build a chord progression
Chord palette
Click a chord to add it to your progression below. Hover or add a chord to see what it does.
Your progression
Each chord shows its length. In this time signature you can fit up to chords per bar. Use the arrows to reorder.
Genre starting points
Presets load into whatever you are editing above, transposed into your key. They replace the current chords.
Step 3 · Plan your song sections
Choose a structure to start with, or build your own. Each section holds its own chord progression, sound pattern, and repeat count.
Step 4 · Listen to your ideas
Step 5 · Reflection journal
