How to Read Sheet Music

Reading Sheet Music

Sheet music, the written form of music notes, may appear very complex to the untrained eye. While reading music notes is like learning a whole new language, it is actually much less complicated than you may think. This article will discuss how to read sheet music.


The foundation of the written musical language is the staff. It is made up of five lines and four spaces, as seen below. The lines are numbered 1-5 starting from the bottom line. The spaces are numbered 1-4 starting with the bottom space (in between lines 1 and 2).

Clefs and Note Names

Each line and space of the staff correspond to a musical pitch, which is determined by the clef. Music notes are named after the first seven letters of the alphabet: A, B, C, D, E, F, G. The two clefs that are primarily used are the treble clef and bass clef.

How to Read Treble Clef

The treble clef, pictured below, is also known as the 'G-clef'. This is because the curve in the clef encircles the second line of the staff, which is called a 'G' on the treble clef staff. The treble clef is used by instruments that have higher registers, like the flute, violin and trumpet. The higher registers of the piano are notated in the treble clef as well. For beginning pianists, notes on the treble clef staff will be played with the right hand.

The note names on the spaces of the treble clef spell out F-A-C-E.

The note names on the lines of the treble clef are E-G-B-D-F. Some mnemonics to help you remember this are "Every Good Boy Does Fine," "Every Good Boy Deserves Fudge," or "Elvis's Guitar Broke Down Friday."

How to Read Bass Clef

The bass clef, pictured in the examples below, is also known as the 'F-Clef' because the fourth line of the staff passes between the two dots. The note located on this line of the bass clef staff is an 'F.' In early music notation, hundreds of years ago, this clef sometimes moved around. The 'F' was located on whichever line passed between the two dots. In other words, the F might have been on the third line instead of the fourth line! Today, the 'F-Clef' does not move around and is known interchangeably as the bass clef.

As its name indicates, the bass clef is used by instruments with lower registers, like the cello, trombone or bassoon. The lower registers of the piano are notated in the bass clef. For beginning pianists, notes on the bass clef staff will be played with the left hand.

The note names on the spaces of the bass clef staff are A-C-E-G. Some helpful mnemonics to remember this are "All Cows Eat Grass" or "All Cars Eat Gas."

The note names on the lines of the bass clef staff are G-B-D-F-A. Some helpful mnemonics to jog your memory are "Good Boys Do Fine Always" or "Good Boys Deserve Fudge Always."

Ledger Lines

Ledger lines are used to notate pitches below or above the regular lines and spaces of the staff. 'Middle C,' one of the first notes beginning music students learn, is located on a ledger line between the bass clef and treble clef staffs. You can see how it is notated in both of these clefs in the examples below.

Ledger lines are used sometimes in music notation because it makes the notes easier to read than constantly changing between clefs. There can be an infinite number of ledger lines above or below any staff, but it can be difficult to read the music if there are more than three. At that point, it is usually wise to change clefs. For example, writing the following on the treble clef staff...

is the same as writing...

Accidentals (Flats, Sharps, and Naturals)

In Western music, an "accidental" may be added in front of the note to change the pitch by a semitone, or half-step.

The symbol pictured below is a flat sign. As its name suggests, this symbol is used to indicate that the pitch of the note should be lowered by a semitone. The note pictured here is a B-flat.

The symbol that looks like a pound sign or hashtag is a sharp sign. It indicates that the note it precedes should be raised by a semitone. The note in the example is a C-sharp.

If a sharp or flat precedes a note at the beginning of a measure, that note remains sharp or flat for the entirety of the measure. So, instead of writing a sharp sign before each note, it is written like this:

Even if there are other notes in the measure, the note that is preceded by a sharp or flat remains sharp or flat in that measure. The notes in the example below read B-flat, C, A, B-flat, even though the last note does not have the flat symbol before it.

If the note is no longer supposed to sound sharp or flat, it will be preceded by a natural sign. The note in the following example is an E-natural.

If we take the exampe above and wish to make the second B-flat a B-natural, it would look like the example below, which reads B-flat, C, A, B-natural.

Remember, accidentals only apply within the given measure. Measures are separated by bar lines, a thin, vertical straight line that passes through the four spaces of the staff, as pictured below.

Take a look at the example below. Because there is a bar line separating the fourth note from the fifth note, the fifth note is actually a B-natural, not a B-flat. The six notes below read B-flat, C, A, B-flat, B-natural, C.

Sometimes a composer or arranger may put a "courtesy" natural (or sharp or flat) at the beginning of the measure, as per the example below. This is a friendly reminder that the previous accidental no longer applies. This sounds exactly the same as the example above.

Key Signatures

In many cases, a composer or arranger may wish for certain notes to be flat or sharp throughout a whole piece, unless otherwise indicated by a natural sign or other accidentals, of course! They will communicate this in sheet music by utilizing a key signature. A key signature defines the key of the music and thus what flats or sharps are supposed to be played throughout the piece. This helps reduce the need for accidentals (i.e. placing a flat or sharp before a note in the music every time it occurs). Now, there are some important rules to know about key signatures. A key signature is made up of sharps or flats, not a combination of the two. Flats and sharps are added in a particular order, as outlined below.

Flats in the key signature lower the pitch of notes on the corresponding line or space by a half-step (or semitone). This transfers to all octaves. Different keys are defined by the number of flats (or sharps) in the key signature, starting with the leftmost and moving to the right. Flats are added to a key signature in the following order: BEADGCF. For example, if there is only one flat in the key signature, it will always be B-flat. If there are three flats, they will always be B-flat, E-flat and A-flat, and so on.

Sharps in the key signature raise the pitch of notes on the corresponding line or space by a half-step. Different keys are defined by the number of sharps (or flats) in the key signature, also proceeding from left to right. Sharps are added to a key signature in the following order: FCGDAEB. For example, if you one sharp in the key signature, it will always be F-sharp. If you have four sharps, they will always be F-sharp, C-sharp, G-sharp and D-sharp, and so on.

A helpful way to remember the order in which flats and sharps are added to a key signature is to recognize that they are the reverse of each other. As you can see in the image below, flats are added to the notes from left to right and sharps are added to the notes from right to left.

Notes on a Piano Keyboard

Many musicians often get their start playing the piano or keyboard. In fact, students who go on to study music in college are required to take a piano proficiency course. It is helpful to have an understanding of the piano keyboard, especially when we discuss scales, in the next section.

This pattern repeats several times on a keyboard. There is a half-step between every key on the piano, whether you are moving from a white key to a black key or a white key to a white key. Even though there is no black key between E and F or between B and C, each pair is still only a half-step apart. Because there is a black between C and D, D and E, etc., we call the distance between those pairs of notes a whole-step.

Remember how we discussed earlier that a sharp raises the pitch of a note by a half-step and a flat lowers the pitch of a note by a half-step? The black keys perform this function on a piano. For example, the black key you see between C and D sounds a C-sharp or a D-flat. Visually, it makes complete sense because the black key is positioned above the C and below the D. The note between D and E is a D-sharp or an E-flat, and so on.

Now that you have a basic understanding of the piano keyboard and the distance between the notes, let's talk about scales!


The order in which flats or sharps are added to a key signature is so important because, in Western music, much of the melody and harmony of a piece is built using the notes of a single scale. Scales are a set of notes ordered by a combination of whole steps and half steps. There are several types of scales in the musical language; this article will focus on major and minor scales.

Major Scales

First, let’s take a look at the written C-major scale. This particular scale has no sharps or flats. It would also be played solely on the white keys of a keyboard.

C-major scale:

All major scales are comprised of the following pattern of tones: whole-step, whole-step, half-step, whole-step, whole-step, whole-step, half-step.

If you were to start the scale on a note other than C, you would need to add sharps or flats to maintain this pattern of tones. Let’s take a look at the F-major scale.

F-major scale:

As you now know, there is a whole-step between A and B, but in a major scale, that distance needs to be a half-step. Therefore, we lower the pitch of the B by a half-step to B-flat. (For the record, in a written scale, you never have two notes containing the same letter name. In the F-major scale, you would never see the B-flat written as an A-sharp.)

Now that we’ve looked at a scale with a flat, let’s take a look at a sharp scale.

D-major scale:

The distance between the second and third notes of a major scale is a whole-step. Since there is only a half-step between E and F, we need to raise the F by a half-step to an F-sharp. The same is true between the sixth and seventh notes of the scale, which is why there is a written C-sharp.

Minor Scales

Every major scale has a relative minor scale. A relative minor scale shares the same key signature as its major scale, but it begins on the sixth note of the major scale. For example, A is the sixth note of the C-major scale, which makes A-minor the relative minor scale of C-major. Look at the F-major and D-major scales above? What is the relative minor scale for each of those major scales? Hint: find the sixth note of the scale.

Because you are using the same key signature as a major scale, but starting on the sixth note, there is a different pattern of whole-steps and half-steps. Take a look at the A-minor scale below.

A-natural minor scale:

All natural minor scales are comprised of the following pattern of tones: whole-step, half-step, whole-step, whole-step, half-step, whole-step, whole-step.

You may be wondering why this scale is called A-natural minor, and not simply A-minor. That is because there are three types of minor scale. The natural minor scale makes no alteration to the notes in the indicated key signature; in other words, there are no accidentals.

In the harmonic minor scale, the seventh note of the scale is raised by one half-step. In the A-harmonic minor scale, the G becomes a G-sharp.

A-harmonic minor scale:

The third type of minor scale is the melodic minor scale. This one is a bit tricky, because it is different ascending than descending. (All scales discussed previously are the same ascending and descending.) In the melodic minor scale, the sixth and seventh notes of the scale are raised by a half-step going up and return to their original pitch, as indicated by the key signature, on the way down.

A-melodic minor scale:

An extremely helpful device to remember all of the different major and minor scales and their flats or sharps is called the Circle of Fifths. This is the best friend of many students studying music theory.
