+
+## Goals for This Week
+- **Goal 1:** Design and implement a slider for manual cent adjustment
+- **Goal 2:** Develop functionality for cent adjustment system
+- **Goal 3:** Design and implement mode-specific icons for the tuner interface
+
+
+---
+
+## This Week's Achievements
+
+1. **Mode-Specific Icon Design and Implementation**
+   - Created distinctive icons for both tuning modes
+   - Successfully integrated icons into the tuner interface
+   - Ensured visual consistency with existing Music Blocks design language
+
+2. **Manual Cent Adjustment Interface Redesign**
+   - Transitioned from pie menu to slider-based interface
+   - Implemented basic slider UI for cent adjustment
+   - Designed interface to accommodate ±50 cents range
+   - Optimized for both recorded and uploaded samples through the sampler
+
+3. **Cent Adjustment System Development**
+   - Implementing core functionality for precise pitch adjustment
+   - Developed system to handle cent adjustments within ±50 range
+   - Created framework for real-time pitch modification
+
+4. **Integration and Testing**
+   - Successfully integrated new components with existing tuner system
+   - Conducted initial testing of slider functionality
+   - Verified icon visibility and clarity in different modes

+
+## Challenges & How I Overcame Them
+
+- **Challenge:** Maintaining precise control over cent adjustments while ensuring smooth slider operation
+- **Solution:** Implemented a custom scaling algorithm and added intermediate value snapping for better control
+
+
+---
+
+## Key Learnings
+- Gained deeper understanding of real-time audio processing in web applications
+- Discovered best practices for handling micro-pitch adjustments in digital audio systems
+- Enhanced knowledge of Web Audio API's capabilities and limitations
+
+---
+
+## Next Week's Roadmap
+- Conduct extensive testing with various audio sources and instruments
+- Process free/open samples from identified sources
+- Design basic categorization system for samples
+- Write Week 06 blog post summarizing progress and learnings
