+# Week 02 Progress Report by Anvita Prasad
+
+**Project:** [Music Blocks - Improve Synth and Sample Features](https://github.com/sugarlabs/musicblocks/issues/4539)  
+**Mentors:** [Walter Bender](https://github.com/walterbender)

+
+## Goals for This Week
+- **Goal 1:** Design dual-mode tuner interface
+- **Goal 2:** Research and prototype cents adjustment UI
+- **Goal 3:** Investigate temperament systems and EDO implementations
+- **Goal 4:** Implement visual feedback system for pitch detection
+
+---
+
+## This Week's Achievements
+1. **Researched Dual-Mode Tuner Design**
+   - Analyzed requirements for two proposed tuning modes:
+     - Specific Target Pitch mode with fixed reference
+     - Arbitrary mode with dynamic ±50 cents range detection
+   - Started working on UI mockups for both modes
+   - Researching effective visual feedback systems for pitch deviation
+
+2. **Implemented Initial Cents Adjustment Feature**
+   - Created basic manual cents adjustment UI
+   - Exploring alternative UI approaches for better user experience
+   - Studying various tuner implementations (e.g., [F-Droid's Tuner](https://f-droid.org/en/packages/de.moekadu.tuner/)) for inspiration
+
+3. **Developed Tuner Visualization System**
+   - Implemented center-outward segment lighting system
+   - Left/right segments indicate flat/sharp notes respectively
+   - Number of lit segments shows pitch deviation magnitude
+
+4. **Pitch Detection System Research**
+   - Studied advanced pitch detection methodologies
+   - Researched FFT spectrum analysis and phase information evaluation
+
+---
+
+## Key Learnings
+- Gained deep understanding of Equal Divisions of the Octave (EDO) systems and their implementation challenges
+- Learned about various temperament systems (Equal, Just, Werckmeister, Kirnberger)
+- Studied advanced audio processing techniques including FFT window optimization and spectrum phase analysis
+- Researched UX patterns for precise musical instrument tuning interfaces
+- Explored different approaches to visual feedback systems for micro-pitch detection
+
+---
+
+## Next Week's Roadmap
+- Complete tuner implementation with accurate visualization
+- Finalize and implement the selected cents adjustment UI design
+- Write Week 03 blog post summarizing progress and learnings
