Curly Maple is not a species of wood, but it one of the most famous grain variations of the maple heartwood that is today prized as one of the best wood types for the creation of musical instruments (most notably guitars, violins and other string instruments).
The grain of maple achieves this effect because the fiber cells that grow from the depths of its root to the tops of its canopy twists and turns as it grows, creating a wave-like effect that can be exaggerated in the finished lumber if it is cut in a certain way. The most common way of achieving this stunning grain pattern is by processing maple lumber with the quartersawn tool. Simply cutting a maple using flatsaw will create a much-subdued version of a curly maple grain design, and often erase all presence of it.
The 3D-like effect of curly maple is known as “figure”, and it represents a distortion that is perpendicular to the grain’s direction.
The wood of curly maple is commercially harvested from the maple trees from the diverse Sapindaceae family that consists of around 128 individual species. Majority of those species are natively originating from Asia, but dozens of them have also managed to spread their roots across Europe, North America, and northern Africa. Only one species of maple ( Acer pseudoplatanus) can be found in the southern hemisphere, and the most common species of this tree that is found across almost entire in Europe is Acer pseudoplatanus.
The vast majority of maple species types are deciduous trees, while a minority are shrubs and just a few of them can live evergreen around Mediterranean region and southern Asia. Around the world, the maple tree and its leafs have managed to become famous symbols. Most notably, Canadian flag features Maple leaf, which in this case signifies endurance and strength.
The height of use of curly maple for furniture peaked in 18th-century colonial America. Tiger maple variation also has a strong history in the world of violin makers. They used this wood type so extensively, that maple got another name because of it - fiddle maple.
The defining characteristic of curly maple grain is the fascinating design of its grain pattern that manages to create an interesting illusion of a three-dimensional pattern in which it appears that the grain is curling along the length of the entire board. The exact reason for the irregular growth of fiber cells inside maple tree’s heartwood is not currently known to scientists.
As are many other things in nature, there is not only a single type of a curly maple design. Different looking stripes can be achieved not only with different wood cutting methods but also because of the internal characteristics of the wood itself. The differences in grades of the curly maple design are one of the defining reasons for the existence of different price points of curly maple wood. The subdued effect can be purchased cheaply, but visually striking designs can reach a price of some of the most exotic wood types on the modern market. The markers that define the cost of curly maple are the frequency of the curls (most prized ones are closely-spaced curvy designs), color (lightness and uniformity, bright and even designs are most popular), and intensity between three-dimensional objects and surrounding wood. However, the majority of curly maple wood designs are still not reaching the price of some other types of maple wood. For example, soft maple wood that was cut with flatsawn and produces a perfect “quilted maple” design is prized almost above all available types of curly maple.
In addition to the name curly maple, this type of wood is also known as rapid grain maple, flame maple, ripple maple, tiger stripe, fiddleback, and others.

Curly maple is considered to have six official figure designs, with three additional ones being regarded as side-types. All eleven types of maple figure designs are used extensively today.
Six primary curly maple figure variations are:

Curly maple is prised all around the world for its beautiful appearance and can be found not only in musical instruments but also in many other high-end household items that are created both using machining and hand tools. Maple trees are also extensively used outside for commercial purposes.
