Building a Carnatic Music Practice AppPublic

Since this is a new project, I need to understand your preferences before designing the architecture. Let me ask a few key questions.

Now I have a clear picture. Let me design the architecture for this Carnatic music practice web app.

Now let me write the final plan to the plan file.

I've created a comprehensive plan for building your Carnatic music practice app. The key points are:

What you'll get:

• Web app with React + TypeScript + Tailwind
• Settings for base pitch (C-B as Sa), BPM, gati (1/2/4 notes per beat)
• Sarali Varisai 1-14 to start, expandable to Janta/Dhatu/Melsthayi/Alankarams
• Tanpura drone that follows your selected pitch
• Real-time pitch detection showing which swara you're singing + cents deviation
• Post-practice feedback: accuracy %, which notes were wrong, timing analysis

Technical approach:

• Uses pitchy library for pitch detection (accurate for voice)
• Web Audio API for microphone + tanpura synthesis
• Hz → Swara mapping using Carnatic just intonation ratios
• 60fps detection loop for precise timing analysis

Excellent! Let me start building the app. I'll create tasks to track progress and begin with the project setup.

Now let me create the TypeScript types and data files.

Now let me create the Zustand store.

Now let me create the audio modules.

Now let me create the practice engine hook and UI components.

Now let me create the UI components.

Now let me create the main App component.

Let me install the dependencies and verify everything works.

Now let's start the dev server to make sure everything works.

The app is now running at http://localhost:5173/

Here's what I built for you:

Carnatic Practice App

Features Implemented:

1. Settings Panel

   • Base pitch selector (C through B as Sa) with kattai reference
   • BPM control (20-120)
   • Gati/speed selector (1x, 2x, 4x notes per beat)
   • Tanpura toggle

2. Exercise Selection

   • Sarali Varisai 1-14 (all patterns included)
   • Category dropdown for future exercises

3. Notation Display

   • Shows swaras in grid layout with measure bars
   • Animated cursor moves through notes during practice
   • Upper/lower octave indicators (dots above/below)

4. Tanpura Drone

   • Synthesized tanpura using Web Audio oscillators
   • 4 voices: Sa (two octaves), Pa, with subtle LFO modulation
   • Follows your selected base pitch

5. Pitch Detection

   • Real-time microphone analysis using pitchy library
   • Cent-level precision showing sharp/flat deviation
   • Live feedback display during practice

6. Post-Practice Feedback

   • Overall accuracy percentage
   • Timeline showing correct/incorrect notes
   • Problem areas highlighting which swaras need work

How to Use:

1. Open http://localhost:5173/
2. Select your base pitch (e.g., D for Sa)
3. Adjust BPM and speed
4. Choose an exercise (Sarali Varisai 1-14)
5. Click "Start Practice"
6. Allow microphone access when prompted
7. Sing along with the moving cursor
8. After completion, review your feedback

To add more exercises later:

• Add Janta Varisai to src/data/exercises/jantaVarisai.ts
• Add Dhatu/Melsthayi/Alankarams similarly
• Import and register in src/data/exercises/index.ts
