Building a Carnatic Music Practice AppPublic

Good, I have a better understanding now. The site has:

• Sarali Varisai, Janta Varisai, Dhatu Varisai, Melsthayi Varisai
• Alankarams (7 tala patterns)
• Geethams and Swarajatis
• Varnams
• Pitch settings (F, F#, G, G#, A, A#)

This is a complex app. Let me enter plan mode to properly design this.

Since this is a new project (not an existing codebase), I don't need to explore existing code. Instead, I need to:

1. Understand the requirements better
2. Design the architecture
3. Ask clarifying questions about technology choices

Let me ask the user some key questions about their preferences for the tech stack and specific features.

The user wants:

• Web app
• Visual notation + audio (tanpura drone, reference tones)
• Cent-level precision (can show sharp/flat within a note)
• No gamaka detection (plain notes only)

Now I need to design the architecture. Let me launch a Plan agent to help design this, and also think about the technical approach myself.

Key components:

1. Frontend: React or vanilla JS web app
2. Audio Input: Web Audio API + pitch detection library (like pitchy, pitchfinder, or ml5.js)
3. Audio Output: Web Audio API for tanpura drone + reference tones
4. Music Data: JSON structures for ragams, compositions (sarali varisai etc.)
5. Analysis: Compare detected pitches with expected notes, calculate timing accuracy

Let me create a comprehensive plan.

That's a comprehensive design from the Plan agent. Now let me write this into the plan file and then exit plan mode for user approval.

Let me create the plan file with a concise, actionable summary.

Good, I've written the plan. Now I should exit plan mode to get user approval.

The user has approved the plan. Now I can start implementing. Let me create the tasks and start building the app.

I'll start with:

1. Phase 1: Project setup + data
2. Phase 2: Settings + Exercise UI
3. And so on...

Let me create the tasks first, then start implementing.

Now let me start with task #1 - setting up the project.

The operation was cancelled, probably because the directory is not empty. Let me check what's in the directory and create the project properly.

The directory only has the .claude folder. Let me try creating the project with the --yes flag or by specifying that it should overwrite.

It seems like the npm create command is having issues. Let me try a different approach - I'll manually create the project files.

The npm create vite command is not working. Let me try creating the project in a subdirectory or manually create the necessary files. I'll just create all the files manually since that's more reliable.

Good, dependencies are installed. Now let me set up all the necessary config files and project structure.

Now let me create all the config files and project structure.

Good progress. Now let me create the src directory structure and main files.

Now let me create the main entry files and CSS.

Now let me create the types and data files. These are the foundation of the app.

Now let me create the data files for swaras, ragams, and exercises.

Now let me create the Zustand store and then the UI components.

Now let me create the audio modules - TanpuraSynth and PitchDetector.

Now let me create the UI components and the practice engine hook. I'll complete the core functionality first.

Now let me create the UI components.

Now let me create the main App component to tie everything together.

Now let me install the dependencies and run the app to make sure it works. Let me also update the tasks.

Good, dependencies installed. Now let me run the build to check for any TypeScript errors.

There are a few TypeScript errors. Let me fix them.

I need to fix the TypeScript errors:

1. Remove unused Swara import
2. Fix the Float32Array type issue by using explicit casting
3. Remove unused SWARA_CENTS import from the hook

Now let me fix the usePracticeEngine hook by removing the unused SWARA_CENTS import.

I need to remove the unused import SWARA_CENTS from the hook file.

Now let me run TypeScript check again.

The Float32Array type is still an issue. Let me try a different approach - using as any or casting properly.

Let me just use as any to bypass this type issue, since the runtime behavior will be correct.

Let me check TypeScript again.

The error is on line 67 which is the getFloatTimeDomainData call, not the findPitch call. Let me read the file again to see the current state.

The issue is with getFloatTimeDomainData. This is a standard Web Audio API method and the TypeScript typing might be off. Let me skip strict typing for this file by using a type assertion.

Let me check TypeScript again.

Let me try a different approach - disable type checking for this specific operation or use a different cast.

Let me check TypeScript again.

TypeScript passes. Now let me run the dev server to make sure the app actually works.

The dev server is running. The app is ready to use at http://localhost:5173/. Let me provide a summary to the user.
