Story-Driven Lesson Plan Framework for Music Blocks

[stutijain2006]

Overview
This PR introduces an initial prototype for integrating lesson plans directly into Music Blocks through a story-driven learning experience.
The goal is to move beyond text-heavy instructional activities and explore a more engaging format for the primary Music Blocks audience (ages 7–11). Rather than presenting lessons as isolated exercises, this approach connects them through an ongoing narrative where learners progress through a world by solving music-based challenges.
This prototype is intended to gather feedback on both the technical implementation and the educational direction before additional lesson plans are developed.

What's Included
Lesson 1 and Lesson 2 Integration
Implemented the first two lesson levels within the existing lesson framework:
Level 1: Hot Cross Buns – Discover the Form
Level 2: Sakura Sakura – Discover the Melody
These lessons remain based on the original musical learning objectives while introducing narrative context and progression.

Exploration Badge System
This PR also experiments with rewarding curiosity rather than only rewarding lesson completion.
Examples include:

• Modifying melodies
• Exploring different octaves
• Trying alternative musical ideas
• Creating variations of provided patterns
  Instead of explicitly instructing learners to perform these actions, rewards appear when exploration naturally occurs.
  The intention is to encourage experimentation and discovery while maintaining focus on the lesson objectives.

Motivation
During discussions about lesson plans, a recurring concern was that younger learners may find long instructional text difficult to engage with.
This prototype explores an alternative approach where:

• Lessons are presented as chapters in an ongoing story.

• Progression is tied to narrative outcomes.

• Exploration is encouraged through optional rewards.

• Learning objectives remain embedded within musical activities.
  The goal is to make Music Blocks feel less like a sequence of tasks and more like an interactive adventure.
