## What you would see

The instrument stands upright and centered, seen from the front, against a seamless background that shifts from black at the top to light gray at the bottom. Soft studio light casts a faint shadow beneath its base and brings out the sheen of the wood. It is a rectangular box or board, taller than it is wide, made of reddish-brown wood with visible vertical grain, fine scratches, and a surface polished through handling. The top edge dips into a concave curve, like a shallow crescent, with both ends rising to points. From that upper area, numerous short, pointed prongs project upward. Across the front extend roughly sixteen long, dark iron tines, parallel and of unequal length; the central ones reach farther down, forming an irregular lower edge. They are held by a lighter horizontal wooden bar and by a metal rod crossing the instrument. Twisted wire is visible at both sides. Round, dark metal studs, evenly spaced, border the sides and bottom, almost like a dotted frame. Its exact scale cannot be determined from the photograph, although the object appears made to be held in the hands.

## How to look at it

First follow the long metal tines from top to bottom and notice how their uneven ends create a rhythm of their own. Then look at the row of round studs framing the wood, almost like punctuation. The contrast between the warm, worn board and the dark, slender iron changes the object from a simple board into a resonant instrument.

## Context

According to the source, this is a lamellophone, also called a “thumb piano,” made by an unknown maker in the 1900s and attributed to a Bushoong-style maker in the Democratic Republic of Congo, in Central Africa. It is made of wood, iron, and upholstery studs, and belongs to the African Art department of the Cleveland Museum of Art, as part of the Charles G. King Jr. collection, gifted by Ralph King in his memory. Lamellophones produce sound when flexible tongues are plucked, usually with the thumbs, while the body amplifies the vibration. The maker's name, the exact use of this example, and its original tuning are not known from the available data.

## Curious detail

In a lamellophone, the length of each tine affects its pitch: in general, longer tongues vibrate more slowly and sound lower, while shorter ones sound higher.

## Questions

- What melodies or rhythms might the arrangement of long and short tines have made possible?
- How do the studs, twisted wire, and polished wood change our perception of an instrument meant to be heard?
- What is lost when an instrument is shown in silence, without hands, sound, or its original setting?

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. Count the dark parallel tongues on the front, about how many are there?
2. What color is the main wood of the body that looks polished with vertical grain?
3. What small round metallic element borders the side and bottom edge like a dotted frame?
