View source for RPD's Simplified Elementary Notation

'''RPD's Simplified Elementary Notation''' is the successor to the experimental [[Hexbinmos' Elementary Notation]] created by [[Fel2Fram]] and [[Hexbinmos]] from [[FPSB]]. [[RPD]], an [[SPSC]] member and pen spinning researcher, had developed it since reading the original elementary notation between 2012-2013.

Like in Hexbinmos' work, it defines a series of elementary tricks and a grammar for describing all tricks and combinations in pen spinning.

==Tricks==
The count of tricks in RPD's system is reduced down to 5<ref>Gonzalez, D. (2021). Pen spinning history and notation. pp.51-53</ref> compared to Hexbinmos' 6 elementary tricks, with "Stall half-release" being omitted in favor of reusing Fingerswitch combined with a fingerless slot. The characters used to reference them have also been changed from the original Greek letters to those from the Latin alphabet.

===a Fingerswitch===
A spinless change of slots, the fingers and hand move but the pen remains stationary.

===b Tipped Charge===
A tipped charge-like motion. The rotation about the slot is clockwise for the normal and counter-clockwise for the reverse.

===c Wiped Charge===
A wiper-like motion, that can be performed in the center of the pen as well as at the ends.

===d Roll===
Rolling the pen along its long axis, without changing a slot.

===e Slide===
A sliding motion to move the pen more towards the inside or outside of a slot, without changing the slot.

==Grammar==
The notation system borrows its grammar from formal notation. Tricks are connected in a linear sequence to begin with, with slots notated after the name of the trick. For instance:
 a T1-T2 > a t2-12
Note the ">" borrowed from Hexbinmos' notation, equivalent to "->" in formal notation.

Simultaneous tricks and rotations can also be applied:
 b+c 0.25 23 > a+b rev+c 0.25 23-13
With the tricks occurring simultaneously notated with "+" before the slots. Note how the rotation section immediately after refers to both tricks at once. This is because a notated trick block covers an identical time period for all simultaneous tricks, with a minimum timing difference between tricks of 0.25 rotations. Note also the postfix "rev" referring to a trick being performed in reverse.

Fingerless slots are notated with "*", either on its own for a true aerial or with fingers to indicate a fingerless trick is being performed while in contact with them:
 (PD) c 0.5 1234*

==Examples==
RPD provided several example notated tricks in his book using the system.

===Pass===
 Pass 12-23 = a+b 0.25 12-13.2>23

===Charge===
 charge = b+c 0.25 > b rev+c 0.25 > b rev+c rev 0.25 > b+c rev 0.25
 charge rev = b rev+c 0.25 > b+c 0.25 > b+c rev 0.25 > b rev+c rev 0.25
Note that the minimum a charge can be split down into is four separate parts, as the direction of one of the constituent charge motions changes every quarter turn.

===Sonic===
 sonic = b+c 0.25 23 > a+b rev+c 0.25 23-13 > a+b rev+c rev 0.25 13-12 > b+c rev 0.25 12
 sonic rev = b rev+c 0.25 23 > a+b+c 0.25 23-13 > a+b+c rev 0.25 13-12 > b rev+c rev 0.25 12
Like the charge, except now adding the fingerswitches also.

===Around===
 IA 12-12 = a+b rev 12-1*>12
 TA T1-T1 = a+b rev+c rev T1-T*>T1
 backaround 12-12 = (PD) Fl a+b+c 12-1*>12
 Bust = (PD) Fl a+b rev+c rev 12-1*>12
 Inverse bust = Fl a+b rev+c 12-1*>12
A variety of examples, with tricks such as inverse bust being highlighted as noteworthy by RPD as the notation can reveal differences between the tricks.

===Spin===
 palmspin = (PU) c rev P*
Here the amount of continuous wiped charge can be omitted as it may vary between varying lengths of palmspin.
