The piano keyboard is the single clearest visual representation of how notes are organized in music. Every note is laid out in a line, in order, with no duplicates or ambiguity. On a guitar, the same note exists in multiple places. On a saxophone, the relationship between fingerings and pitch isn't intuitive. On a piano, it's all just right there.

This is why almost every music theory resource you'll encounter uses a keyboard to explain concepts. You probably already noticed multiple piano keyboards in the last lesson! Spend a few minutes getting comfortable with the layout now, and everything that follows will be easier.

You don't need to be a piano player, nor do you need a keyboard handy to poke around on for this, though of course, both of those things would help.

You need to understand:

• The repeating pattern of white and black keys
• How the groups of 2 and 3 black keys help you find your way around
• Where middle C is
• That the keyboard is just the same 12 notes repeating in higher and lower octaves

That's it. You don't need to play anything. You just need to be able to look at a keyboard and know what you're seeing.

Articles

• All About Music Theory — Piano Keys Layout — Written by Michael New. Clean, illustrated walkthrough of the keyboard layout... probably the only resource you actually need here.

• Wikipedia — Musical keyboard — Dry, but thorough. Good reference if you want the full technical picture. Has more information than you need, but if you're into it knock yourself out.

Interactive tools

• musictheory.net — Keyboard Note Identification — Interactive exercise: it highlights a key, you name the note. Great for drilling after you've learned the layout. The lessons section also has a structured walkthrough of the basics.

• muted.io — Virtual Piano & Theory Tools — Interactive music theory references: virtual piano, chord and scale lookups, cheat sheets. Good for poking around.

If you have access to a piano, keyboard, or even a free piano app on your phone — find middle C. Find the groups of 2 and 3 black keys. Play from C to the next C (one octave). Notice that the pattern repeats.

Don't have a keyboard handy? Use our virtual keyboard right here on Melos — find middle C, play up an octave, and get a feel for the layout.

If you want to drill note names, use the musictheory.net keyboard exercise to quiz yourself until you can get 10 in a row without hesitating.
