Edwin Edwards and List of musical symbols: Difference between pages

This is intended to be a comprehensive guide on the various symbols encountered in modern sheet music.

Lines

	Staff The background structure of a musical score. Lines and spaces correspond to different notes on the diatonic scale. For example, on the treble staff, the lowest line is E above middle C (E4 in note-octave notation). The space above it is F4, and so on. A common use of the staff is the grand staff, which combines bass and treble staffs into one system, joined by a brace.
	Ledger lines Used to extend the staff if any note heads fall above or below it. Such ledger lines are placed behind the note heads.
	Bar line Used to separate two measures.
	Double bar line Used to separate two sections of music.
	Dotted bar line Subdivides measures.
	End bar line Marks the end of a song.

Notes and rests

Note and rest values are not absolutely defined, but are proportional in duration to all other note and rest values. For the purpose of definition, the duration of the quarter note will be known as R, for "reference length."

Note	Duration	Rest
	Longa Also known as a "quadruple whole." This value is archaic. Duration: R × 16
	Breve Also known as a "double whole." This value is archaic. Duration: R × 8
	Semibreve Also known as a "whole." Duration: R × 4
	Minim Also known as a "half." Duration: R × 2
	Crotchet Also known as a "quarter." Duration: R
	Quaver Also known as an "eighth." Duration: R / 2
	Semiquaver Also known as a "sixteenth." Duration: R / 4
	Demisemiquaver Also known as a "thirty-second." Duration: R / 8
	Hemidemisemiquaver Also known as a "sixty-fourth." Duration: R / 16
	Quasihemidemisemiquaver Also known as a "hundred-twenty-eighth." Duration: R / 32
	Beamed notes Beams connect and emphasize quavers and shorter note values.
	Dotted note Putting dots to the right of a note head fine-tunes that note's duration. One dot lengthens the note by one-half, two dots by three-quarters, three dots by seven-eighths, and so on. Rests can be dotted in the same way as notes.
	Multi-measured rest Indicates how many measures to sustain a rest.

Pauses

	Breath mark In a vocal score, this symbol tells the singer to breathe in.
	Caesura Tells the performer to silence his or her instrument completely.

Clefs

Clefs define the pitch range, or tessitura, that the staff after them represents.

	G clef The centre of the spiral defines the line or space it rests on as the note G above middle C, or approximately 392 Hz. Positioned here, it assigns G above middle C to the second line from the bottom of the staff, and is known as a "treble clef."
	C clef This clef points to which line or space represents middle C, or approximately 262 Hz. Positioned here, it makes the centre line on the staff middle C, and is known as an "alto clef."
	F clef The line or space between the dots in this clef denotes F below middle C, or approximately 175 Hz. Positioned here, it makes the second line from the top of the staff F below middle C, and is known as a "bass clef."
	Neutral clef Used for pitchless instruments, such as those used for percussion. Each line can represent a specific percussion instrument within a set, such as in a drum set. Two different styles of neutral clefs are pictured here.

Clefs (not neutral clefs) can also be modified by octave numbers. An eight or fifteen above a clef raises the intended pitch range by one or two octaves respectively. Similarly, an eight or fifteen below a clef lowers the pitch range by one or two octaves respectively.

Accidentals and key signatures

Accidentals modify the pitch of the notes that follow them on the same position on the staff.

	Double flat Lowers the pitch of all forthcoming notes on that level by two semitones.
	Flat-and-a-half Lowers the pitch of all forthcoming notes on that level by three quarter tones.
	Flat Lowers the pitch of all forthcoming notes on that level by one semitone.
	Demiflat Lowers the pitch of all forthcoming notes on that level by one quarter tone.
	Natural Cancels any previous accidental on that level.
	Demisharp Raises the pitch of all forthcoming notes on that level by one quarter tone.
	Sharp Raises the pitch of all forthcoming notes on that level by one semitone.
	Sharp-and-a-half Raises the pitch of all forthcoming notes on that level by three quarter tones.
	Double sharp Raises the pitch of all forthcoming notes on that level by two semitones.

Key signatures define the principal triad of all notes that follow them. If no key signature is used, the default key is C major/A minor. The key signature examples shown here are used with the treble staff.

	Flat key signature Lowers the pitch of all forthcoming notes on the levels the accidentals fall on. Different keys are denoted by differing numbers of accidentals; for example, if only the first two flats are used, the key is Bb major/G minor.
	Sharp key signature Raises the pitch of all forthcoming notes on the levels the accidentals fall on. Different keys are denoted by differing numbers of accidentals; for example, if only the first four sharps are used, the key is E major/C# minor.

Time signatures

Time signatures define the meter of the notes that follow them.

	Specific time The top number indicates the length of a measure in 'beats', and the bottom number indicates which note value acts as a beat. For example, a four indicates that a quarter note represents a beat.
	Common time As the name suggests, this is the most-frequently-used time signature. It indicates 4/4 time.
	Cut time Indicates 2/2 time.
	Metronome mark Written at the start of a score, this symbol precisely defines the tempo of the score by assigning absolute durations to all note values within the score. In this particular example, the performer is told that 120 crotchets, or quarter notes, fit into one minute of time.

Articulations

	Tie Indicates that the two notes joined together are to be played as one note. This can also indicate a note sustained over two or more measures.
	Slur Indicates that the two notes are to be played in one physical stroke.
	Legato Notes covered by this sign are to be played with no gaps. Sometimes indistinguishable from a slur.
	Glissando A steady glide from one note to the next.
	Ligature Also known as a phrase mark.
	Triplet Condenses three notes into the normal duration of two notes. If the involved notes are beamed, the brackets on either side of the number can be omitted. This can be generalized to a tuplet, where a certain number of notes are condensed into the normal duration of the greatest integer power of two notes less than that number, e.g., six notes played in the normal duration of four notes.
	Chord Two or more notes played simultaneously.
	Arpeggio Like a chord, except the notes are played one at a time in sequence. Also known as a rolled chord.

Dynamics

Dynamics are how the volume of the song varies while it is performed.

	Mezzo-piano Half as soft as piano.
	Piano Soft.
	Pianissimo Very soft.
	Mezzo-forte Half as loud as forte.
	Forte Loud.
	Fortissimo Very loud.
	Sforzando A strong, sudden increase in volume.
	Crescendo A gradual increase in volume. Can be extended under many notes to indicate that the volume steadily increases during the playing of those notes.
	Diminuendo A gradual decrease in volume. Can be extended the same way as crescendo.

Accents

Accents specify how individual notes are performed.

	Staccato Buffered by a short silence before and after the note.
	Staccatissimo Buffered by a longer silence before and after the note.
	Marcato The note is within its own articulation.
	Pizzicato A note on a stringed instrument where the string is plucked rather than bowed. The pluck is done with the hand not holding the bow. On horned instruments, this accent indicates a "stopped note".
	Snap pizzicato On a stringed instrument, a note played by stretching a string away from the frame of the instrument and letting it go, making it "snap" against the frame.
	Natural harmonic Played on a stringed instrument.
	Tenuto A sustained note.
	Fermata An indefinitely-sustained note.
	Sull'arco On a bowed string instrument, the note is played while drawing the bow upward.
	Giù arco Like sull'arco, except the bow is drawn downward.

Ornaments

Ornaments modify the pitch pattern of individual notes.

	Trill A rapid alternation between the specified note and the next higher semitone within its duration. Also called a "shake." When followed by a wavy horizontal line, this symbol indicates an extended, or running, trill.
	Mordent An insertion of the semitone below the specified note within its value (this particular case can be called a "lower mordent"). Without the vertical line, the inserted semitone is above the specified note, and the ornament is known as an upper mordent.
	Turn Also known as a gruppetto, combines an upper mordent and a lower mordent, in that order, into the specified note's value. If the symbol is reversed, the lower mordent is played first.
	Grace note Also known as an appoggiatura, it means the first half of the principal note's duration has the pitch of the grace note.
	Slashed grace note Also known as an acciaccatura, it means the principal note's duration begins with the pitch of the grace note for only a very small part of the principal note's value.

Octaves

	Ottava alta Notes under the dashed line are played at the next higher octave.
	Ottava bassa Notes under the dashed line are played at the next lower octave.
	Quindicesima alta Notes under the dashed line are played two octaves above normal.
	Quindicesima bassa Notes under the dashed line are played two octaves below normal.

Pedal marks

Pedal marks are used by pianists.

	Engage pedal Tells the pianist to put the sustain pedal down.
	Release pedal Tells the pianist to let the sustain pedal up.
	Variable pedal mark Denotes frequent use of the sustain pedal. The lower line tells the pianist to keep the sustain pedal depressed for all notes it appears under. The inverted "V" shape indicates the pedal is momentarily released, then depressed again.

Repetition and codas

	Tremolo A rapidly-repeated note. If the tremolo is between two notes, then they are played in rapid alternation.
	Repeat signs Enclose a passage that is to be played more than once. If there is no left repeat sign, the right repeat sign sends the performer back to the start of the song.
	Simile marks Denote that preceding groups of beats or measures are to be repeated.
	Volta brackets Denote that a repeated passage is to be played in different ways on different playings.
	Da capo Tells the performer to repeat playing of the song from its beginning. This is followed by al fine, which means to repeat to the word fine and stop, or al coda, which means repeat to the coda sign and then jump forward.
	Dal segno Tells the performer to repeat playing of the song starting at the nearest segno. This is followed by al fine or al coda just as with da capo.
	Segno Mark used with dal segno.
	Coda Indicates a forward jump in the song to its ending passage, marked with the same sign. Only used after playing through a D.S. al coda or D.C. al coda.
