The Harp
The harp is one of the oldest musical instruments in the world, with evidence of harp-like instruments dating back over 5,000 years to ancient Mesopotamia and Egypt. Its angelic, resonant tone has made it a symbol of beauty and elegance across cultures.
Types of harps: The two main families are the lever harp (or Celtic harp), typically with 22–36 strings and small levers to change pitch by a semitone, and the pedal harp (or concert harp), which has 47 strings and seven foot pedals that each raise a string's pitch by a semitone or whole tone — allowing full chromatic play in any key. The concert harp is the largest and most complex, standing nearly 1.8 metres tall and weighing about 30 kg.
String colour coding: On every concert harp, C strings are red and F strings are black (or dark blue). This universal colour scheme helps harpists navigate 47 strings at a glance, much like the black keys on a piano mark the groups of sharps and flats.
How sound is produced: Each string is tuned to a specific note. When plucked with the fingertips, the string vibrates and the sound resonates through the hollow soundboard. The length and thickness of each string determines its pitch — longer, thicker strings produce lower notes, while shorter, thinner strings produce higher notes.
Playing techniques: Harpists use all eight fingers (never the thumbs) to pluck strings. Key techniques include glissando — sweeping across the strings to create a cascading wash of sound, one of the harp's most iconic effects. Other techniques include arpeggios (broken chords), harmonics (touching the string at its midpoint while plucking to produce a bell-like tone), and bisbigliando (a gentle tremolo effect).
Keys and tuning: This virtual harp offers multiple key selections (C Major, G Major, D Major, F Major, Bb Major, and more). Each key tunes the strings to the notes of that scale across three octaves, so every note you play sounds harmonious together — perfect for improvisation and learning.
Cultural significance: The harp appears in the mythology and art of virtually every civilisation — from the ancient Sumerian lyres of Ur to the Irish national emblem, the Brian Boru harp. It features prominently in orchestral music, Celtic folk, ambient, and film scores. Composers like Handel, Debussy, and Tchaikovsky wrote iconic harp parts that remain central to the orchestral repertoire.
Frequently Asked Questions
Why are some strings red and some black?
This is standard concert harp string colour coding. C strings are red and F strings are black (or dark blue) on every real harp. It helps players navigate the instrument quickly without looking at labels, much like the black keys on a piano.
What is a glissando?
A glissando is a continuous sweep across adjacent strings — the signature gesture of harp music. On a real harp, the player brushes their fingers across the strings in one fluid motion. Here, swipe your finger or pointer horizontally across the harp and each string fires as you cross it.
Why does the Pentatonic key sound so good for glissandos?
The pentatonic scale (C D E G A) contains no semitones or tritones, so any combination of its notes sounds consonant. On a real harp, pentatonic and whole-tone tunings are used specifically for glissandos that always sound musical regardless of which notes are struck.
What do the dots on the strings mean?
The small red circles mark the midpoint of each C string — another navigation aid used on real harps. They help players locate octaves quickly during fast passages.
How many strings does this virtual harp have?
The number of strings depends on the selected key. C Major shows 22 strings (three diatonic octaves, C3 to C6). Pentatonic shows 16 strings (five notes per octave over three octaves). A real concert harp has 47 strings (B0 to G♯7).
What are the samples used?
