New to Music? Here's Everything You Need to Know (From Someone Who's Been Playing for Nine Years!)

Starts

Hi, my name is Haritha and I'm a current junior in high school! I've been involved in music since third grade and play flute, violin, and piano. I'm also a jazz musician and have received multiple accolades for my improvisation!
In this session, we'll cover how to name notes, identify them on a standard keyboard, read notes on the alto, tenor, treble, and bass clefs. With this background knowledge, you will be able to learn any instrument far more easily!

Hey, writers! My name is Madison Threatt and I decided to create a safe space for you to share your creativity. I am currently hosting a creative writing series called "If you are CREATIVE, then this is for YOU!". It will be session 3 out of 5 which is happening on Nov 22 (you can still join if you want).

This series, however, is just a set aside time for you to work on your piece. Whether it's a book, short story, etc, it is a time for you to just write.

We'll bounce ideas off each other and just let our creativity flow. It's just for fun! I'll even be working on my own book and you can do your own thing.

Life can be very busy but this time is dedicated to finishing your work.

Weekend Trip to the Brain

Starts

Have you ever wondered why your brain does what it does? 🧠 Each week, I’ll dive into one part of the brain and explain what it does in a simple, fun way. Understanding your brain helps us understand ourselves better – how we think, feel, and act – and can even help you become a better student 📚 by showing how you learn, focus, and process information. I’ll share tips 💡, explain real-world phenomena 🌎, and connect everything to everyday life, including how music 🎵 affects the brain.

You can expect interactive sessions with chances to ask questions ❓, share ideas 💬, and join discussions. Each session will end with a Kahoot 🎮 to review what we learned and keep it engaging. My goal is to make neuroscience approachable and help you see the brain in a whole new way! 🌟
