In the arts, a "note" refers to a fundamental unit of communication, expression, and documentation across multiple disciplines. In music, a note denotes a specific pitch and duration within a system of notation. In literature and visual arts, a note can be a brief written observation, a marginal annotation, or a preliminary sketch that captures an idea or comment. The concept bridges technical precision (e.g., musical notation) with creative spontaneity (e.g., an artist's sketchbook note), serving as both a building block of composition and a record of creative process.
1 Musical note
A musical note is a symbol representing a sound of a given pitch and duration. It forms the basic building block of melodies, harmonies, and rhythms in Western and many world music traditions. Notes are written on a staff or other notation system and can be modified by accidentals (sharps, flats, naturals) and expressive markings.
1.1 Pitch and frequency
Pitch refers to the perceived frequency of a sound wave, measured in hertz (Hz). In standard tuning, the note A4 (the A above middle C) is set to 440 Hz. Higher frequencies produce higher pitches, while lower frequencies produce lower pitches. The relationship between pitches is logarithmic: doubling the frequency raises the pitch by one octave.
1.1.1 Naming conventions (A–G, solfège)
In Western music, pitches are named with the letters A through G, repeating cyclically. Accidentals (♯ sharp, ♭ flat) modify the pitch by a semitone. Solfège is an alternative system used for sight-singing, associating syllables (do, re, mi, fa, sol, la, ti) with scale degrees. Movable do assigns "do" to the tonic of a key; fixed do assigns "do" to C.
1.1.2 Octave registers
Octave registers group notes whose frequencies are in a 2:1 ratio. The register is indicated by a number following the note letter (e.g., C4, C5). Middle C is C4. The International Standards Organization (ISO) system uses numbers 0–8 for the piano range. Each octave spans twelve semitones (the chromatic scale).
1.2 Duration and rhythm
Duration determines how long a note is held. Rhythm is the pattern of durations and silences in time. Notes are notated with different shapes to indicate relative length, and rests indicate silence.
1.2.1 Note values (whole, half, quarter, etc.)
Note values are fractions of a whole note (semibreve). Common values include: whole note (4 beats in 4/4 time), half note (2 beats), quarter note (1 beat), eighth note (½ beat), sixteenth note (¼ beat). Smaller subdivisions are also used. The shape of the notehead, stem, and flags or beams distinguish the values.
1.2.2 Ties, dots, and rests
A tie connects two notes of the same pitch, combining their durations. A dot after a note increases its duration by half (e.g., a dotted quarter note equals a quarter plus an eighth). Rests indicate silence of a specific duration, using symbols corresponding to note values (whole rest, half rest, quarter rest, etc.).
1.3 Notation systems
Notation systems provide a visual representation of music. Different systems serve different instruments, genres, or purposes.
1.3.1 Staff notation
Staff notation uses five horizontal lines and four spaces, with a clef (treble, bass, alto, tenor) indicating the pitch range. Notes are placed on lines or spaces to show pitch; stems, beams, and flags show rhythm. Additional symbols (key signature, time signature, bar lines) organize the music.
1.3.2 Tablature
Tablature (tab) shows finger positions on an instrument rather than pitches. Common for guitar, lute, and bass, it uses horizontal lines representing strings and numbers indicating frets. Rhythm is often indicated by stems or noteheads above the tab lines. It is more intuitive for players than staff notation in some contexts.
1.3.3 Graphic notation
Graphic notation uses non-traditional symbols, shapes, lines, and drawings to represent sound. Used extensively in experimental and avant-garde music, it allows for indeterminate or open interpretation. Examples include works by John Cage and Cornelius Cardew, where performers translate visual elements into musical actions.
1.4 Expressive markings
Expressive markings indicate how a note or passage should be performed beyond pitch and duration, affecting volume, attack, or ornamentation.
1.4.1 Dynamics
Dynamics indicate loudness or softness. Common markings: *pp* (pianissimo, very soft), *p* (piano, soft), *mp* (mezzo-piano, moderately soft), *mf* (mezzo-forte, moderately loud), *f* (forte, loud), *ff* (fortissimo, very loud). Gradual changes are shown by crescendo ( < ) and decrescendo ( > ).
1.4.2 Articulation
Articulation markings shape how a note begins and ends. Examples include: staccato (a dot over the note, short and detached), legato (slur, smooth connection), accent ( > , stronger attack), tenuto (a short horizontal line, hold full value), and marcato (^, emphasized).
1.4.3 Ornaments
Ornaments (or embellishments) add decorative notes to a melody. Common ornaments include: trill (rapid alternation between the written note and the note above), mordent (quick alternation with the note below), turn (a sequence of notes circling the main note), and appoggiatura (a grace note that takes part of the main note's duration).
2 Written note in literature
In literature, a note is a brief written text that records information, commentary, or reflection. It may be private or public, formal or informal, and appears in various forms from personal writing to scholarly apparatus.
2.1 Personal notes (diaries, journals)
Personal notes are informal records kept by individuals for self-reflection, memory, or planning. They are typically not intended for publication and are written in a private, spontaneous style.
2.1.1 Intimate reflections
Intimate reflections are notes that explore personal emotions, relationships, and inner thoughts. Diarists like Anne Frank and Samuel Pepys used such notes to document daily life and emotional states. These notes often reveal the author's private self and can become valuable historical documents.
2.1.2 Travel notes
Travel notes record observations, impressions, and experiences during journeys. They may include descriptions of places, people, customs, and personal reactions. Famous examples include the travel journals of Charles Darwin and Mark Twain. Travel notes often evolve into published travelogues or serve as source material for other works.
2.2 Annotations and marginalia
Annotations are notes added to a text, typically in the margins or between lines. They provide commentary, clarification, or interpretation by a reader or scholar.
2.2.1 Scholarly glosses
Scholarly glosses are explanatory notes written by academics or editors, often found in editions of classical or medieval texts. They elucidate difficult terms, references, or historical context. Glosses can be interlinear (between lines) or marginal, and sometimes form a running commentary alongside the primary text.
2.2.2 Reader's marginal notes
Marginal notes made by readers are personal reactions, questions, or connections. These informal annotations are common in study Bibles, textbooks, and literary works. They reflect the reader's engagement and can be studied to understand reception history. Famous annotated readers include Samuel Taylor Coleridge and Virginia Woolf.
2.3 Literary footnotes and endnotes
Footnotes and endnotes are formal notes placed at the bottom of a page or at the end of a chapter or book. They provide supplementary information without interrupting the main text.
2.3.1 Citation notes
Citation notes give credit to sources, indicating the author, work, page number, or other bibliographic details. They follow style guides (e.g., MLA, Chicago, APA) and are essential for academic integrity. Footnotes allow immediate reference, while endnotes keep the page cleaner but require flipping.
2.3.2 Author's commentary
Authors sometimes use notes to add personal remarks, clarifications, or asides. Notable examples include the extensive footnotes in David Foster Wallace's *Infinite Jest* and the satirical endnotes in Vladimir Nabokov's *Pale Fire*. These notes can become a narrative device, playing with the boundary between text and commentary.
3 Note in visual arts
In visual arts, a note is a quick, often preliminary representation of an idea, observation, or composition. It can be a sketch, a color study, or a written observation within an artist's notebook.
3.1 Preliminary sketches and studies
Preliminary sketches are rough drawings made to explore a concept before creating a finished work. They are often free, experimental, and gestural.
3.1.1 Gesture notes
Gesture notes capture the essential movement, posture, or energy of a subject with rapid, loose strokes. Common in figure drawing, they emphasize action over detail. Artists use them to quickly record a pose from a model or a fleeting scene from life.
3.1.2 Color notes
Color notes are small studies that test color combinations, light effects, and tonal relationships. They may be painted on a small scale in oils, watercolors, or pastels. Impressionist painters like Claude Monet made numerous color notes outdoors (plein air) to capture changing light conditions before executing larger canvases.
3.2 Artists' notebooks
Artists' notebooks are bound volumes where artists compile sketches, written ideas, observations, and experiments. They serve as a personal laboratory for visual thinking.
3.2.1 Leonardo da Vinci's codices
Leonardo da Vinci's notebooks (codices) are among the most famous examples. They contain thousands of pages of anatomical studies, mechanical inventions, architectural plans, and natural observations, often accompanied by mirror-written text. They illustrate the note as a tool for interdisciplinary exploration.
3.2.2 Modern sketchbooks
Modern artists continue the tradition of keeping sketchbooks. Examples include the intimate sketchbooks of Frida Kahlo (full of self-portraits and personal symbolism) and the graphic diaries of Keith Haring. Digital sketchbooks using tablets and styluses have also emerged, allowing layers, undo, and easy sharing.
3.3 Annotation on artworks
Notes can be physically placed on or near artworks to provide context, interpretation, or provenance information.
3.3.1 Exhibition labels
Exhibition labels are notes affixed to the wall next to a displayed work. They usually include the artist's name, title, medium, date, and a brief curatorial statement. Some labels also include QR codes linking to audio guides or extended essays.
3.3.2 Curatorial notes
Curatorial notes are more extensive written materials (wall texts, catalog essays) that explain the themes, history, or significance of an exhibition or individual piece. They are often the result of research and are intended to educate and engage the viewer.
4 Note in performing arts
In performing arts, notes document instructions, movements, cues, or choreographic patterns. They are essential for reproduction and consistency in performances.
4.1 Stage directions
Stage directions are notes in a play script that describe actions, movements, setting, and technical effects. They guide directors, actors, and technical crews.
4.1.1 Blocking notes
Blocking notes specify the movements and positions of actors on stage. They are often written in the margins of a script during rehearsals. Typical notations include "cross downstage left," "enter from upstage right," or "kneel center stage." Directors may create detailed blocking charts.
4.1.2 Lighting and sound cues
Lighting and sound cues are notes that indicate when and how lighting or sound effects should change. Cue numbers, timing (e.g., "after line 15"), and descriptions (e.g., "fade to blue") are recorded in a cue sheet. These notes are used by technicians during performances.
4.2 Choreographic notation
Choreographic notation systems record dance movements in a symbolic form, allowing dances to be preserved, reconstructed, and studied.
4.2.1 Labanotation
Labanotation, developed by Rudolf Laban, uses abstract symbols on a vertical staff to represent body parts, directions, levels, and timing. It can capture complex movement sequences with high precision. It is used by choreographers and dance scholars.
4.2.2 Benesh movement notation
Benesh movement notation, invented by Joan and Rudolf Benesh, uses a five-line staff and symbols placed on a representation of the human body. It records the positions and movements of the dancer in space. It is commonly used in ballet and contemporary dance.
5 Digital notes and ephemera
Digital notes are electronic records created and stored on computers, tablets, or smartphones. They range from simple text memos to multimedia files, and they often have a transient or informal character.
5.1 Digital annotation tools
Digital annotation tools allow users to add notes to electronic documents, images, or web pages. Programs like Adobe Acrobat, Notability, and Hypothes.is enable highlighting, sticky notes, text comments, and drawing. These tools are used for study, collaborative editing, and research.
5.2 Multimedia notes (audio, video)
Multimedia notes incorporate audio recordings, video clips, or photographs. Voice memos are audio notes captured on smartphones; video notes are short clips used for visual demonstrations or reminders. They are often integrated with note-taking apps like Evernote or OneNote.
5.3 Social media as informal notes
Social media platforms such as Twitter, Tumblr, and Instagram serve as informal spaces for note-like content. Short posts (tweets, reblogs, stories) can capture fleeting thoughts, observations, or reactions. Hashtags organize these digital notes into searchable themes. Memes, a form of humorous image-based note, spread rapidly and reflect internet culture. These ephemeral notes are often archived or deleted, embodying the transient nature of digital communication.
