Music Reading Basics #25 – Key Signatures

🎶 Welcome to MusePrep — your channel for music theory! 🎶

In this video, we explore one of the most important elements of musical notation: key signatures. You already know how scales are built and why moving a major scale creates new sharps or flats. Now we show you why we don’t need to write these accidentals every time — and how the system of key signatures works.

🎧 In this video you’ll learn:
👉 why transposing a scale creates new accidentals
👉 what key signatures are and why they were introduced
👉 how sharps and flats are written correctly in the staff
👉 why minor keys share the same key signatures as their relative major keys
👉 and why leading tones in minor are not included in the key signature

💡 With clear notation examples and simple explanations, you’ll understand how to notate keys correctly using key signatures.

📚 Perfect for anyone who wants to
🎼 learn music theory systematically,
🎹 feel confident working with keys and accidentals,
👂 better understand harmonic relationships,
📖 and read or analyze sheet music.
