music theory

Welcome! I am so excited to help you dive into the world of music. Before we map out our journey, tell me a bit about what brings you here. Do you play an already, or are you starting completely from scratch?

It is wonderful to have you here! Since you are starting completely from scratch, we will take things one step at a time, beginning right at the very beginning. Let's start by looking at what actually is.

At its core, music theory is simply the language we use to understand, describe, and communicate how music works. Just like learning to speak a new language, we start with the absolute basic building blocks before we try to write a masterpiece.

Are you ready to explore our very first musical building block?

Yes, continue to the concept of pitch

Let's jump right into our very first musical building block: pitch. Simply put, is how high or low a sound is. Think of it as the vertical map of music. When you press a key on the far right of a piano, you get a high, bright sound like a bird chirping. When you press one on the far left, you get a low, deep rumble like thunder. In physical terms, pitch is determined by the speed of vibrations. Fast vibrations create high pitches, while slow vibrations create low pitches. Every instrument you play uses some method—like tightening a string or shortening a tube—to change these physical vibrations and let you choose which pitches to play.

To keep all these high and low pitches organized, we use a naming system. In the next step, we will look at how we label these sounds so we can start making patterns with them.

Are you ready to meet the musical alphabet?

Continue to the 12-note musical alphabet

Welcome to the musical alphabet! While our spoken alphabet has 26 letters, the musical alphabet is beautifully simple: it has only seven basic letters. We use the letters A, B, C, D, E, F, and G to name our pitches. Once we reach G, we do not go to H. Instead, the pattern simply loops back to A and starts all over again, climbing higher and higher like a spiral staircase. This repeating distance from one letter to its next matching letter (like A to the next A above it) is called an .

But you might be thinking: if there are only 7 letters, where do the rest of the 12 notes come from? To fill in the gaps between some of these letters, we use symbols called accidentals—specifically and .

A sharp ( $\sharp$ ) raises a note by a half-step (the very next adjacent sound).
A flat ( $\flat$ ) lowers a note by a half-step.

These symbols let us access the five extra "in-between" notes to complete our 12-note system.

Continue to mapping these 12 notes to a keyboard

Now that we have our 12 notes, let's see where they actually live! The absolute best way to visualize these notes is on a standard , which acts as a perfect physical map of music theory.

Take a look at how the keys are arranged. You will see a repeating pattern of white keys and black keys.

The white keys are our basic letter notes: A, B, C, D, E, F, and G.

The black keys are grouped in repeating patterns of twos and threes. These black keys represent our five in-between notes (the sharps and flats).

Notice that there are two places on the keyboard where there is no black key separating the white keys: between B and C, and between E and F. In music theory, these notes are naturally only a half-step apart, meaning they are immediate neighbors with no room for a sharp or flat in between!
