Understanding Piano Notes

One of the biggest obstacles that musicians and producers face is understanding piano notes.

Luckily, the basics of piano music theory aren’t as scary as they may seem. 

Music theory is a technical skill that can be learned by anyone. It’s a skill that has many patterns to make learning easier.

This translates into learning the piano notes and their relation to the piano keys. Once you highlight the patterns, it becomes clearer.

If you’re a beginner musician looking to pick up the piano, or a music producer who is trying to build better MIDI for your track, it’s important to understand the different piano notes and how they work together.

Piano Notes

In today’s guide, we’re diving deep into the different piano notes and keys, their layout, how they’re used in chords, some basic sheet music, and finishing off with some tips to get you to your musical goals faster. Let’s dive in!

The Musical Alphabet

The musical alphabet is a term used to describe the 7 natural piano notes together. 

It consists of the letters A, B, C, D, E, F, and G, which relate to specific piano keys. It is cyclical, meaning that after the G, the alphabet cycles back to the A and goes again. One cycle represents a single octave, which is a range of pitches in relation to one another.

Piano Notes - The Musical Alphabet

The repetition makes it possible to play a wide range of music on the piano, and in theory, can be repeated an infinite amount of times in either direction. However, in reality, there are only so many piano keys available.

Each piano note in the alphabet represents a specific pitch, determined by its position on the piano. So, within a single octave, note A is the lowest in pitch, whilst note G is the highest in pitch.

White Piano Keys

As discussed, the musical alphabet covers the natural notes of an instrument. In piano music theory, these natural notes are the white piano keys.

The 7 white piano keys follow the musical alphabet left to right, in alphabetical order. So starting on note A, it moves through all of the white keys to reach note G. 

White Piano Notes - Piano Keys

Again, this covers a single octave, and if you were to continue playing piano keys in the same direction, you would be moving up one octave.

Black Piano Keys

The 5 black piano keys represent sharp or flat notes, which have a slightly different pitch than the natural white keys. These notes are often called accidentals.

Each black piano key gives off a note that is half a step higher (sharp) or lower (flat) than the white key next to it.

Sharp piano notes are symbolized by the # sign, whilst flat piano notes are represented with a ♭sign.

So for instance, starting on the white key of C, if we play the black piano key to the right of it, that is C sharp (C#). If we started on the white key of D and went to the black key to the left of it, that would be D flat (Db).

Each black note can represent either a sharp or flat note, depending on the relationship of the other notes in the sequence and scale.

Piano Keys Layout

A piano keyboard layout has repeating patterns of 12 keys, which consist of the 7 white keys and 5 black keys mentioned above.

This pattern is a single octave, and a piano will have multiple octaves across its piano notes. Each octave contains the same set of 12 notes but at different pitch ranges.

Layout of all Piano Notes

The Order of Piano Keys

To understand the order of the piano keys, we can simply reference the musical alphabet.

Playing from left to right, you will be able to follow along, including the black keys as the half steps in between the white piano keys.

Start with the white note A, half stepping up to the black key of A#, moving next to the white note of B, and so forth. 

The Middle C and Hand Position

If you have taken any music theory or piano lessons, you may have heard the teacher reference the Middle C. 

The Middle C, as you may have guessed, is the white piano key C note that is just left of the group of 2 black keys. Whilst it’s not exactly in the middle of the piano layout, it is the closest C note to the middle.

The Middle C is an important reference point as it is the point at which our two hands meet when playing the piano.

Middle C and Hand Position - Piano Notes

Piano notes played lower than the Middle C will be played by our left hand. 

Piano notes played higher than the Middle C will be played by our right hand. 

Understanding hand position is crucial if you are looking to play piano notes accurately and comfortably. 

The most common hand position for most people is the C Major position. This is where your right-hand thumb sits on the Middle C, and your fingers on both hands sit on the white keys that are adjacent. 

The Middle C is also a reference point when learning to read sheet music, as pianists and other key-based instrumentalists cover both the higher pitches (treble clef) and lower pitches (bass clef)

On the grand staff above, the bottom section represents piano notes that would be played lower than Middle C, whilst the top section shows the piano notes that would be played higher.

Different Types of Piano

It’s important to understand that there are many different types of pianos, however, the layout of the piano keys remains the same on all these different types.

It’s the number of keys (and octaves), as well as the feel of the keys that will differ depending on the type of piano you are playing.

A typical full-sized piano has 88 piano keys, but there are traditional pianos that range from 44 all the way up to 97 keys (such as the Imperial Bösendorfer).

If you are a music producer, this also translates into the different MIDI keyboards that are available, with common sizes including 25, 49, 61, and 88 keys.

You can take your piano skills and theory and apply them to different types of key-based instruments. From a classic grand piano to a digital synthesizer, the patterns remain the same.

Piano Notes and Chords

Once you understand the different piano notes, then you can begin learning (and building) chord progressions.

A chord is a combination of 3 or more notes that are played at the same time. In music theory, this is called creating harmony.

For beginner musicians learning to play the piano, triad chords are often a good starting point, as they consist of only 3 notes.

For instance, if you play the C major chord in the Major Scale, you’ll notice you are pressing 3 natural, white piano keys (C, E, and G).

C Major Chord

For all types of music artists, chords are a powerful tool to add more depth and character to your song arrangement. Regardless of the instrument, the patterns that chords follow remain the same on each instrument.

There are more complex chord structures that can add more unique characteristics to your sound, such as seventh chords, among many others.

Different chord structures, progressions, and the different musical modes are entirely separate topics that you will need to spend time learning once you have the basics of piano notes and music theory nailed down.

Piano Keys and Piano Sheet Music

Musicians who are serious about playing the piano need to understand how to read piano sheet music. 

Sheet music provides a visual representation of the different piano notes to be played, along with other important factors, such as the music’s rhythm and key.

When reading piano sheet music, you read from left to right (as you would a book), and play the different types of musical notes in order.

Different Musical Notes

The Different Musical Notes

There are a few core elements that makeup sheet music, which we have broken down below:

The Staff

Firstly, the musical staff is a set of 5 lines (with 4 spaces in between) that you will come across on piano sheet music.  These lines can be thought of as the foundations when reading piano sheet music. 

Single Staff lines Example

Different musical notes are placed on and/or between the lines. The higher the note is on the staff, the higher its pitch.

These notes can also be placed above and below the 5 main lines, using what’s called ledger lines. This ledger lines can be seen on the last 2 notes in the B Major sequence below.

B Major Scale - Staff


At the start of the staff, you will see a clef, which is a particular symbol that represents a pitch range for the notes to follow.

The most common clefs that pianists will come across are the treble clef and the bass clef. 

The treble clef (also known as the G clef) represents higher-pitched notes. These notes are generally played with the right hand

The bass clef (also known as the C clef) represents lower-pitched notes. These notes are generally played with the left hand

F Major Grand Staff

Key Signature

After the clef, you will also come across the key signature, which determines which key the following music is to be played in.

A key signature appears as either a single or cluster of flat/sharp notes, that corresponds to a particular scale. The only scale that does not feature any key signature is the C Major Scale which is left blank.

Here’s an example of the G Flat Major Scale key signature:

G Flat - Key Signature

Key signatures help musicians prepare for the key of the music before they begin to play, so that they can play the right melody. They also keep the staff from being cluttered with sharp and flat notes after every note.

Time Signature

Finally, the time signature is placed after the key signature and indicates how many beats per measure and the length of each beat. 

The most common time signature is 4/4, which represents 4 beats per measure at a quarter note beat length. 

Time signature - piano notes

When you play the piano (or any instrument) from sheet music, it’s crucial to understand what time signature you are playing in, so that you can interpret the music’s rhythm

Tips for Learning Piano Notes

With this newfound knowledge of piano notes and their relationship to one another, use the following tips to test your music skills:

Start with the basics: Focus on learning the musical alphabet, white and black piano notes, and the layout of the keyboard.

Learn different scales: If you haven’t mastered this already, take some time to learn about the different major scales and minor scales.

Use flashcards: Create flashcards with images of piano keys and their corresponding note names to test your knowledge and reinforce learning.

Practice regularly: Consistent practice is key to mastering piano notes. Try to practice at least once a day, even if it’s just for 10-15 minutes.

Learn chords: Familiarize yourself with basic chords to expand your knowledge of piano notes and improve your overall musicianship.

Research sheet music: Go and find sheet music of songs you already know, this way you can better understand the relationship between musical notes and the piano keys to play. 

Summary – Mastering Piano Notes

And there you have it, our deep dive into piano notes and keys. 

Every aspiring musician and producer needs to build a solid understanding of the piano basics. Understanding how to read, interpret and play different piano notes will demonstrate the relationships of different keys, notes, and chords in a way that sheet music cannot. 

It is also a fundamental skill if you want to write your own melodies, build songs, work with other musicians, and much more. 

Although it can seem overwhelming as a beginner, with regular practice and some discipline, you’ll be on your way to mastering the piano and its notes in no time.
