No. The harp is a string instrument. Its sound comes from a stretched string, and that is the only thing any classification system asks about. Everything else — how you touch it, where the player sits, what it looks like — is decoration.
The harp belongs to the string family, in every system that classifies instruments
Formally it is a chordophone — Hornbostel–Sachs 322–5, “composite chordophone sounded by the bare fingers”. In an orchestra it is counted with the strings. There is no scheme, scientific or orchestral, that files the harp under percussion. The question comes up for reasons that are real but have nothing to do with what the instrument is.
What decides an instrument’s family is what vibrates
The system musicologists actually use, Hornbostel–Sachs, has five classes. Percussion is not one of them.
| Class | What makes the sound | Examples |
|---|---|---|
| Idiophone | The body of the instrument itself | Cymbal, xylophone, triangle, cowbell |
| Membranophone | A stretched skin | Snare drum, timpani, bass drum |
| Chordophone | A stretched string | Harp, violin, guitar, piano |
| Aerophone | A vibrating column of air | Flute, trumpet, harmonica, bagpipes |
| Electrophone | Electricity | Synthesiser, theremin |
Striking appears in that system, but as a subdivision inside each class rather than as a class of its own. A struck skin is a struck membranophone. A struck bar is a struck idiophone. A struck string is still a chordophone. So “percussion” describes a way of playing and a section of an orchestra — it is a job description, not a family.
Which means the harp never had a case to answer. Forty-seven strings under tension, plucked with the pads of eight fingers: string instrument, and not a marginal one. The same test sorts every other instrument you might wonder about, and there is a fuller walk through it in our guide to the instrument families.
The piano is the instrument that proves the rule
A piano has hammers. Press a key and a felt hammer flies at a string and hits it. If striking a string were enough to make an instrument percussion, the piano would be the clearest case on earth.
It is classified 314.122-4-8: a simple chordophone with a keyboard, sounded by hammers. A string instrument, with the striking recorded as a detail of how it is played. If actual hammers do not move an instrument out of the string family, ten fingertips certainly do not.
The piano is also where the two ways of talking visibly part company. Plenty of orchestras hand the piano chair to the percussion section, because a pianist in a symphony plays like a percussionist does — occasional entries, counted bars, one part among the colors at the back. That is a rota, not a reclassification, and it is a large part of why the same question gets asked about the harp sitting a few feet away. We put the two instruments side by side in harp vs. piano.
Why the harp looks like it is in the percussion section
Because on most seating charts it is standing in the same row. The harp goes at the back on the conductor’s left, alongside the piano, the timpani and the rest of the percussion, and a printed seating plan will often group all of them onto one line.
The reasons are practical. The harp plays in the same register as the upper strings and woodwinds and spends most of its time decorating their lines, so it wants to be near them. It is quiet, so it needs to be kept clear of the brass, which would swallow it. And harp parts are full of cues that have to be caught from the conductor, so the player needs a clean sight line. Put those three requirements together and the harpist ends up at the back left — visually among the drums, musically with the violins.
Notation software adds its own confusion. Several scoring programs file the harp under pitched percussion in their instrument lists, next to the marimba and the tubular bells, which is a decision about how the software groups staves rather than a statement about the instrument.
The harp does get hit — and it is still a string instrument
This is the part with a genuine grain of truth in it. Twentieth-century harp writing is full of percussive effects, most of them codified by the harpist Carlos Salzedo: knocking on the soundboard, slapping the flat of the hand against the low wire strings for a gong-like crash, and the technique he named xylophonic sounds, where a finger stops a string near its base while the other hand plucks it, producing a dry wooden knock instead of a ringing note.
A harpist doing all of that is playing percussively on a string instrument. So is a guitarist slapping the body between chords, and nobody moves the guitar. What an instrument is and what a player does to it are separate questions, and only the first one decides the family.
A harp is a string stretched between two points, and always has been
The oldest harps that survive are bow harps: a curved wooden arm with strings running along the inside of the curve into a hollow body, unmistakably the shape of a hunting bow. There is no soundboard trickery and no mechanism — just tension between two ends of a stick, which is the definition of a chordophone with nothing left over.
Everything since has been an answer to one problem: a harp string plays one note, so a harp needs as many strings as it has notes, and changing key means changing strings. Levers and pedals exist to solve that, and they are the only real difference between the instruments below.
Three instruments are sold as harps, and only two are harps
The same geometry that settles the family question also settles which of these is which. On a harp the strings rise away from the soundboard at close to a right angle and pass through it. On a lyre they lie flat across the face of the instrument and cross a bridge, the way a guitar’s do.
| Lyre “harp” | Lever harp | Pedal harp | |
|---|---|---|---|
| Actually a harp? | No — it is a lyre | Yes | Yes |
| Strings | 7–19 | 22–38 | 47 |
| Strings meet the soundboard | Flat across it, over a bridge | At a right angle, through it | At a right angle, through it |
| Range | 1–2 octaves | 3–5 octaves | 6½ octaves |
| Changing key | Retune string by string | Flip levers between pieces | Move pedals mid-bar |
| Weight | 2–4 lb | 11–30 lb | About 80 lb |
| Price | ~$80 | ~$150–$1,500 | $15,500 and up |
If the answer made you want to try one
Donner DLH-003, 16-String Lyre Harp
- 16 steel strings
- G3–A5, two octaves, tuned to C major
- Mahogany, hollow resonance box
- Tuning wrench, spare strings and gig bag included
- ~$100
Sold as a lyre harp, and it is a lyre: the strings lie across the soundboard over a copper saddle rather than rising out of it. That is not a criticism at the price. It is the most enjoyable eighty dollars in this whole subject, it sounds good within an hour, and sixteen strings is enough to carry a folk tune where a seven-string runs out of notes halfway through.
The same model is sold in 7-string and 10-string versions too, so check the string count before you order. The tone is bright and metallic, nearer a zither than the soft wash the word harp suggests — that is what steel over a small box sounds like, and it is true of every lyre at this money. Our lyre vs. harp comparison takes the distinction apart properly, and the lyre harp guide puts this one against the alternatives.
AKLOT 15-String Harp
- 15 strings, two octaves
- Mahogany, about 21″ long and 15″ tall
- Strings knotted through the soundboard, harp geometry
- Tuning wrench, gig bag and strap included; no spare strings
- ~$150
Harp-shaped and harp-strung — a closed frame with a pillar taking the upward pull, and strings that pass through the soundboard rather than over a bridge. Built well for the money, tensioned sanely, and light enough to play on a sofa.
Two octaves and no levers is the limit of it. Both-hands harp technique does not fit into fifteen strings, so treat this as finding out cheaply whether plucked strings make you happy rather than as a first step toward lessons.
Roosebeck Heather Harp, 22 Strings with Chelby Levers
- 22 DuPont hard nylon strings
- C3–C6, three full octaves
- Full Chelby sharping levers on every string
- About 36 inches tall, 11 lb
- Extra strings, tuning tool and play book included
- ~$600
This is where a harp starts being a harp you can learn on. Three octaves is enough room for both hands to work independently, and a lever on every string means you can change key between pieces instead of spending twenty minutes with a tuning wrench. The bundle covers the things a beginner does not know to buy.
Expect a few weeks of daily tuning while new nylon strings stretch and settle — that is every harp at every price, not this one. Our beginner harp guide puts it against five alternatives, and tuning a harp covers the settling-in period.
The concert harp, and what those seven pedals do
The instrument in the orchestra has 47 strings covering six and a half octaves, against a piano’s seven and a quarter. It stands about six feet tall and weighs around 80 lb.
With every pedal up, the strings sound the scale of C♭ major. Three pedals sit under the left foot — D, C and B — and four under the right: E, F, G and A. Each one has three notches. Top is flat, middle is natural, bottom is sharp, and moving a pedal shortens every string of that letter across the whole instrument at once. Two positions per pedal was the older single-action design; Sébastien Érard’s double action, launched in 1811, added the third, and that is what lets a harpist play in any key and change key inside a bar. It is still the mechanism on every concert harp built today. There is more on the mechanism in our guide to the pedals on a harp, and on the choice between the two kinds in lever harp vs. pedal harp.
Frequently asked questions
Is the harp in the string family?
Yes, both ways of counting. Orchestrally it is grouped with the strings; formally it is a chordophone, class 322–5.
Is the piano a string or a percussion instrument?
A string instrument that is often administered as a percussion one. Its strings are struck by hammers, which is why it gets described both ways, but the classification is unambiguous: chordophone.
Is a lyre a harp?
No, though most of the cheap wooden instruments online are sold as “lyre harps”. Both are chordophones, so both are string instruments, but the strings cross a bridge on a lyre and pass through the soundboard on a harp.
Is a blues harp a harp?
No. A blues harp is a harmonica, and it has no strings at all — the sound comes from reeds vibrating in a moving column of air, which makes it an aerophone, class 412.132. The nickname is old slang and nothing more.
Is an autoharp a harp?
No, it is a zither. The strings run flat across a soundboard and are strummed, with chord bars damping everything you do not want. Still a string instrument, still not a harp. We cover them in the autoharp guide.
How many strings does a harp have?
Seven to nineteen on a lyre, 22 to 38 on a lever harp, 47 on a concert pedal harp. The full breakdown is in how many strings a harp has.
Why does the harp sit at the back of the orchestra?
To keep it away from the brass, which would drown it, and to give the player a clear view of the conductor for the cues harp parts are full of. It ends up beside the percussion as a consequence, not as a classification.
So: strings. If the question came from a homework sheet, the answer is the string family. If it came from watching an orchestra and wondering why the harpist is standing next to the timpani, the answer is that they are there for the sight lines.
