Two unrelated instruments are sold as lap harps, and which one arrives depends entirely on which listing you clicked. One is a flat trapezoid box of fifteen strings that you play by sliding a numbered paper sheet underneath them — no notation, no lessons, a tune in about four minutes. The other is a small harp with a pillar and a curved neck that happens to sit on your knee. They cost about the same at the bottom of the range and they have almost nothing else in common.
Most people typing lap harp want the first one. If you want the second, our guide to beginner harps is the page you need.
TK O’Brien’s Original Lap Harp
Fifteen steel strings across two octaves in G, in a hardwood frame with a proper pinblock — which is the part that decides whether an instrument like this holds its tuning or drifts flat between sittings. Three different string gauges, so the bottom octave has some body to it. Eleven songs, a pick, a wrench and a spare string in the box.
Which of the two you are looking at
The test takes one look at the photograph, and it is the same test that separates every harp from every zither: which way do the strings leave the soundboard?
On a harp the strings rise away from the soundboard at right angles, and the frame closes into a triangle — soundbox, neck, pillar. On a song-sheet lap harp the strings lie flat across the face of the box, parallel to it, running from tuning pins along one slanted edge to a rail along the other. There is no pillar because there is nothing to brace against. That makes it a zither, and it puts it in the same family as the autoharp rather than anywhere near the harp.
The name stuck because the sound is close enough — steel strings over a hollow wooden box, plucked bare-fingered, do ring somewhat like a small harp. Nothing about the technique carries over, though. Our lyre and harp comparison works through the same distinction on the other instrument that borrows the word.

How a song-sheet lap harp works
A printed card slides into a slot under the strings. On the card, each note of the tune is printed at the exact point where its string crosses, joined into a path. You pluck the string sitting above each dot, in the order the path runs. That is the whole method. A child can play a recognisable Amazing Grace on first contact, and so can an adult who has never held an instrument.
Because the notes are positions rather than pitches, you are not learning to read music and you are not learning where the notes are. Move the card, and you have no idea what you just played. That is the trade, and it is worth naming plainly before you buy: this is an instrument for playing tunes, not for becoming a musician.
Fifteen strings, two octaves, and why that matters
The Music Maker, the Melody Harp and the TK O’Brien’s are all built to the same plan — fifteen strings covering two diatonic octaves, G up to G, one note per string with no sharps or flats available. Fifteen strings, seven notes to the octave: the arithmetic is the same one that governs every harp’s string count.
That shared layout is the single most useful thing to know about these instruments, because it means song sheets are largely interchangeable between brands. The publishers who sell sheet music for them list the Music Maker, the Melody Harp and the TK O’Brien’s together, and give a physical test for anything else: if your instrument’s cards measure four inches across the top, twelve across the bottom and eight vertically, the sheets will line up. Buy an instrument outside that family and you are limited to whatever music its own maker prints.
One wrinkle sits inside the family. The Melody Harp ships with its F strings tuned to F natural, while the sheets are written for G major and want F sharp. Two strings, one wrench, thirty seconds — but nobody tells you, and until you do it every tune with an F in it sounds subtly wrong.
Steel or nylon
The adult instruments use steel wire. It is bright, it sustains, and it is what produces the bell-like ring people buy these for. It also stays where you put it: steel settles after a few days and then holds for months.
Nylon is softer under a small fingertip and much quieter, which is the entire argument for it on a children’s instrument. The cost is that nylon stretches. A new set will drift for a couple of weeks and want retuning every few days, and it never quite develops the ring. For a three-year-old that is the right compromise; for anyone older it is not. If tuning is the part that worries you, the same clip-on method used on harps works here.
The picks in full
TK O’Brien’s Original Lap Harp
- 15 steel strings
- Two octaves, G to G
- Three different string gauges
- Hardwood frame and pinblock, birch ply top
- Handbuilt in the United States
- 11 songs, pick, tuning wrench, spare string
- ~$70
The pinblock is why this one is worth the extra ten dollars. On a cheap song-sheet instrument the tuning pins are driven into whatever the body is made of, and they creep — you tune it, play it twice, and find it flat again. A dedicated hardwood pinblock is the difference between an instrument you pick up and one you fight with first.
The three string gauges matter more than they sound like they should. Fifteen strings of identical wire across two octaves means the bottom five are floppy and dull; grading the wire gives the low end enough tension to speak. Next to a single-gauge instrument the difference is obvious on the first chord.
Two octaves in G, diatonic, is a real limit — no accidentals, so anything that modulates is off the menu. Within that it plays hymns, carols, folk tunes and nursery songs, which is what the eighteen music packs sold for it consist of.
- Hardwood pinblock, so it actually stays in tune
- Graded string gauges give the low octave some body
- Largest catalogue of matching music of any of these
- A matching padded case exists
- The dearest of the three song-sheet instruments
- Diatonic in G — no sharps or flats
- Two octaves is a hard ceiling once you outgrow it
First Note FN600 Melody Harp
- 15 steel strings
- Two octaves, G to G
- Lacquered hardwood body
- 6 double-sided song sheets — 12 songs
- Tuning key, pick, spare string
- ~$60
The Melody Harp, made under the Grover name, does the same job as the O’Brien’s for ten dollars less, in a lacquered hardwood body that looks handsome enough to leave out on a table. Same fifteen strings, same two octaves, same song sheets.
Where it gives ground is what it does not claim. The O’Brien’s is specified with a dedicated hardwood pinblock and graded string gauges; the FN600 is specified as a lacquered hardwood body and fifteen strings, and the extra ten dollars is what those two features cost. Whether that matters depends on how much you mind reaching for the wrench.
It also arrives with its F strings at F natural rather than F sharp, so budget half a minute with the wrench before the song sheets make sense.
If you are buying to find out whether anyone in the house will actually use it, this is the sensible amount to spend.
- Cheapest full-size steel-strung one worth having
- Inside the Music Maker family, so the song books fit
- Lacquered hardwood, not a painted toy
- No dedicated pinblock or graded gauges
- Needs its F strings raised to F sharp out of the box
- Twelve songs in the box, and no matching case
Hape Happy Harp
- 15 nylon strings
- Two octaves
- 15¾ × 7¾ × 1⅓ inches, 1.8 lb
- Water-based paint, non-toxic finish
- Five song sheets plus a blank one
- Two picks and a tuning wrench
- Age 3+
- ~$45
Nylon strings, a rounded wedge body and under two pounds in weight: this is built for a child who will drop it. It is genuinely tunable rather than a fixed-pitch toy, and the blank sheet is a better idea than it sounds — a five-year-old drawing their own dots on the grid is doing something closer to composition than plucking.
The catch is that it sits outside the Music Maker family. The third-party song books are printed for the fifteen-inch trapezoids and are explicitly not cut for this one, so you are working with the five sheets it comes with and whatever you draw on the blank. For a small child that is usually plenty; for anyone who will still want it in a year, it is a ceiling.
Nylon also means retuning. Expect to reach for the wrench every few days for the first fortnight while the strings settle, and it never rings the way the steel ones do.
- Nylon strings do not hurt small fingers
- Light, blunt-edged and built to survive a toddler
- Properly tunable, not a fixed-pitch toy
- Blank sheet invites a child to write their own
- Third-party song sheets are not cut for it
- Nylon stretches, so it needs frequent retuning
- Quieter and duller than the steel-strung ones
AKLOT 15-String Harp
- 15 nylon strings
- Two octaves, C4–C6
- Red C strings, blue F strings
- Mahogany, satin finish
- About 21 inches long, 15 tall, under 3 lb
- Gig bag, strap and tuning wrench
- ~$150
Same fifteen strings, same two octaves, entirely different instrument. This one has a soundbox, a neck and a pillar, the strings rise off the board at right angles, and you play it with both hands the way you would play a concert harp — which means everything you learn on it transfers upward.
The colored strings are the reason it beats prettier harps at this price. Every C is red and every F is blue, the same code used on every harp built, so you find your place on fifteen identical nylon strings without counting. There are no levers, so it lives in C major and changing key means retuning.
One thing to watch when ordering: the color selector on this listing runs across AKLOT’s whole range, and the cheaper options on it are lyres — a different instrument with no pillar. The mahogany harp is the one described here.
- A real harp, so the technique transfers
- Color-coded strings you can navigate
- Under three pounds, with bag and strap included
- Two full octaves at a price where rivals give one
- Twice the price of the song-sheet instruments
- No levers, so no key changes
- Nothing plays itself — this one needs learning
- No spare strings in the box
What to buy with it
Two things, and only two. More music, because twelve songs runs out fast, and something to keep the dust off the strings.
| Item | What it is | Price band |
|---|---|---|
| World of Harmony, Child’s Play | 28 children’s songs, sized for the Music Maker, Melody Harp and TK O’Brien’s layout | ~$11 |
| TK O’Brien’s padded case | Nylon, handle and shoulder strap, zip pocket. Cut for the O’Brien’s standard harp only | ~$35 |
The case is worth a word of caution: these instruments are all trapezoids and no two makers use the same trapezoid, so a case cut for one will not close over another. Match the case to the instrument rather than to the category. A song book, by contrast, will fit anything in the Music Maker family — which is most of the reason to stay inside it.
What you do not need is a tuner. Every one of these comes with a wrench, and a clip-on chromatic tuner clamped to the frame does the rest; the ones we recommend on our harp tuner page work identically on a zither.
What a song-sheet lap harp will not do
It will not play in another key. Fifteen strings, seven notes, no levers and no way to raise a string mid-tune: whatever it was tuned to is what it plays. Anything with an accidental in it is out.
It will not teach you the harp. The fingering is one finger, one string, one dot at a time, with nothing of the four-finger patterns and hand shapes that harp playing actually consists of. Someone who spends a year on one arrives at a real harp knowing exactly as much as they started with — which is the honest case for spending the extra eighty dollars up front if learning is the goal. Our first-year guide lays out what that path looks like.
And it will not accompany anything. Two diatonic octaves with no bass to speak of is a melody instrument, so it plays the tune and someone else plays everything underneath it.
What it will do is get a tune out of somebody who has never played anything, in one sitting, for the price of a nice dinner. That is not a small thing, and it is why these turn up in classrooms, care homes and hospital wards far more often than in music shops.
Common questions
Is a lap harp a real harp?
The song-sheet kind is not. Its strings lie flat across the soundboard instead of rising away from it, and it has no pillar, which puts it in the zither family alongside the autoharp. The small lever harps also described as lap harps are real harps in every sense — they are simply built short enough to rest on a knee.
How much does a lap harp cost?
A song-sheet lap harp runs about $45 to $70. A genuine harp small enough to play on your lap starts around $150 and rises through $180 for a carved twelve-string to roughly $600 for a twenty-two-string with levers. The gap between the two figures is the gap between the two instruments.
Do I need to read music?
No, and on the song-sheet instruments you never will. The card under the strings shows you which string to pluck and in what order, which is the whole appeal and also the whole limitation.
Will song sheets from one brand fit another?
Within the Music Maker family — Music Maker, Melody Harp, TK O’Brien’s and the older Small World and Yerbonitsa instruments — yes, because they share a string layout. Outside it, no. The quick check is the card size: four inches across the top, twelve across the bottom, eight vertically.
How often does it need tuning?
A steel-strung one settles over the first week or two and then holds for months, wanting a check when the heating goes on or off. A nylon-strung one wants attention every few days at first and every couple of weeks thereafter. Fifteen strings takes about three minutes either way.
Can a young child use one?
From about three, with the nylon-strung one. Steel strings on a small fingertip are unpleasant before six or so, and the steel instruments are heavier and have sharper corners. Our page on harps for children works through the same question for real harps.
How heavy is one?
Under two pounds for a song-sheet instrument, which is why it goes in a bag without a thought. A lever harp you can play on your lap runs from four to eleven pounds, and our page on what harps weigh covers the full ladder.
So which one
If you want tunes this weekend and nobody in the house has played anything, buy the TK O’Brien’s and a song book, and the ten dollars over the Melody Harp buys you a pinblock that will still be holding pitch in five years. If it is a present for a small child, the Hape is the right instrument and its limits will not matter for years.
If any part of you wants to play the harp, spend the $150 on the AKLOT instead. Everything on the song-sheet instruments is a dead end, pleasant as they are, and the year spent on one is a year not spent learning.
Where to go next: beginner harps for the full range of real harps, lyre harps for the third instrument that borrows the name, and autoharps if the zither idea appeals but you want chords under the melody.
