The Basics of Musical Notes

The 7 Musical Notes

The first seven musical notes are: a, b, c, d, e, f, and g. Each of these music notes lasts one beat. The next longest note is the semi-breve, which has a dot and lasts two beats.

This is followed by the half note, which has a vertical line on the right side of the note head, which halves the duration (two beats).


A note has a pitch and a duration. It can also have an accidental, which changes the sound of the note.

The most common accidentals are sharps, which raise the pitch by a semitone or half-step, and flats, which lower the pitch by a semitone or half-step. A note can also have a natural, which cancels the previous accidental.


B is the second note of the musical alphabet and the seventh degree of the natural scale starting from C. It can be either sharp or flat.

A sharp sign looks like a pound or hash symbol and means to go up one note. A flat sign looks like a lower case letter b and means to go down one note.


The letter C is one of the seven musical notes. It is important to learn its pattern because it can make reading music easier.

A whole note (or semibreve) lasts four beats. It has a hollow head and no stem and can be dotted to increase its length. A half note has a stem and lasts two beats. It is often shortened to a quarter note.


The note D sits a fifth above the tonic in this scale. Its technical name reflects this and its relationship to the tonic – ‘dominant’.

Each musical note has a duration or time value. This is the amount of beats it lasts for. It also has a pitch or frequency, which is determined by its octave. This is important for musicians to know.


There are seven musical notes in total. However, the exact sequence depends on which clef you are using.

The first note, called a minim, lasts for 1/2 beat. The next, a crotchet, lasts for 1/4 beat. The third, a semiquaver, lasts for 1/16 beat. And the last, a demisemiquaver, lasts for 1/32 beat.

Each of these musical notes has a different name based on their value and appearance.


A note that is sounded twice as long as the same sound at the next higher octave. A group of notes whose duration exceeds that of a single note is called a chord.

A symbol that indicates a sound that is lowered in pitch by one semitone or half-step. It is written with a sharp sign, as shown above, or a flat symbol.


G is the fifth note of the scale of C major. It also gives its name to the treble clef.

G chords are often one of the first chords people learn to play on lute based instruments like ukulele or guitar. This is because they require only a few fingers to play.

G is also a trademark for a movie rating indicating that it is suitable for all ages.


Guido d’Arezzo’s system made it possible to write music, as well as memorize and reproduce it.

Musical scales use a set of notes that sound harmonic when played one after another.

Symbols like sharp and flat change the frequency of a note, raising it or lowering it by half-step. The letter names are also modified by accidentals. For example, Bb becomes H in German speaking countries.


Musicians use the letters of the alphabet to name notes. There are also symbols called sharps and flats that can change a note’s frequency by one or two semitones.

A sharp looks like a pound sign (hash) and raises the pitch by a half step, while a flat lowers it by the same amount. Learn how to identify these important musical symbols.


A musical note that lasts for two beats. It is the same note as a whole note, only half its length.

Also called breve.

A notation system for string instruments that uses ledger lines to represent pitches above or below the regular lines and spaces of the treble and bass clefs. Middle C, one of the first notes beginning musicians learn to read, is found on a ledger line between the bass and treble clefs.
