**Fingers**

First, we need a way to describe which finger (or fingers to use). This is quite simple, we just state the hand, and then the finger, using a number from 1 (thumb) to 5 (pinkie), which any piano players among you will probably be familiar with. For example:

L3 = left middle finger; R2 = right index finger

To denote multiple fingers, there are a few options:

Fingers are used in a certain order - L2,3

Multiple fingers are used at once: L23

There is a choice between fingers: L2/3

If the turn is a wrist turn, no finger needs to be described

**Grips**

Using this finger notation, we can extend this to grips. To describe a grip, use double slashes. We can use the word “home” for home grip, as it is commonly known, which would look like this:

// Home //

When describing a grip other than home grip, describe the finger, and use an @ symbol to connect it to its location for example:

// [email protected], [email protected] // = Right thumb at UR edge, left middle finger at DR edge.

For centres, UX = U centre, DX = D centre, and so on.

**Turning technique**

Adding one more thing, we can then put it all together to describe an alg. For types of turns:

F = flick

F2 = double flick

Ps = push

Pc = pinch

W = wrist turn

When doing a wrist turn, remember, you do not need to number a finger on the hand, L: W would be a left wrist turn

**How to describe an alg using these notational concepts**

Start the alg by describing a grip, then after each turn, see this example for what to do:

U2(R2,3: F2)

Here, U2 is the turn, R2,3 is the finger(s), and F2 is the technique description.

Something else to note: if the turn you need to describe is the same as the previous turn of its type (e.g. an R2, then later an R2), and the fingertricks are no different, you can put (...) after the turn to show that it is a continuation of the same trick.

I will use this to describe the RUS Ub perm:

// Home // R2’(R: W) U(L2: Ps) R2(...) S(R2: F) R2(...) S’(L2: F) U’(R4: F) R2(...)

Improvements are welcome, this is just an idea I had
