Sonic

Sonics are a category of tricks in which the fingerslot transfer of a pass or fingerswitch is fully accompanied by a conical charge. They often, but not always, end in a different slot than the one they started in. Sonics are among the most versatile and common tricks as they are compatible with almost any style and easily integrate with and hybridize with other trick families. They are also a rich source to use as a diversifying tool as they range from being simple to complex and extremely difficult, with more variations yet to be discovered especially in the field of xpxh.

Variations

Sonic

The baseline Sonic is a fundamental trick that consists of two fingerswitches between three separate slots, while performing one complete conical charge spin. During the second slot the fingers at the extremities solely hold the pen at the same time.

The Inverse Sonic is mechanically the same, but doing it standalone usually includes a total of 2.0 rotations as opposed to only 1.0 rotations in non-Inverse variations. This is due to spinners holding the pen in the same starting position for both tricks despite there being 0.5 rotations of difference in the starting positions if one were to perform them one-to-one. Thus, the initial 0.5 rotations are to achieve the starting position of the Inverse Sonic, 1.0 rotations are performed for the fundamental mechanic, and the final 0.5 rotations bring the ending position of the Inverse Sonic to that of the non-Inverse variations.

Sonic Clip is a term rarely used in practice to denote charges performed in the intermediate slot while the pen is held by the extremities (e.g. performing Charge 13 from a Sonic 23-12).

Pass-based Sonic

These variations transfer fingerslots using a pass. The most common trick of this variation is the Twisted Sonic which has a total of 1.5 rotations and is notated as such: Charge 23 ~ Pass Rev 23-12 ~ Charge 12.

Demon's Sonic

The Demon's Sonic (or Demon Sonic) is a baseline Sonic interrupted with a Twisted Sonic. It is not a specific Sonic variation but rather denotes one specific linkage with the following notation: Sonic 34-24 ~ Twisted Sonic 24-12. Modifiers are almost never used (e.g. Mirrored Demon's Sonic) as those links are often notated in full.

Interrupting a Twisted Sonic with a baseline Sonic yields the Angel's Sonic (or Angel Sonic), but this name is rarely referenced. It is notated as such: Twisted Sonic 34-13 ~ Sonic 13-12.

East Sonic

These variations transfer fingerslots using a fingerswitch but differ from the baseline Sonic as they require four fingers minimum and those on the extremities never solely hold the pen at the same time.

Flush Sonic

These variations involve the transfer of fingerslots using four fingers in which those at the extremities (most likely 14) solely hold the pen at the same time while one of the fingers in the center are fully retracted and the other is fully extended. For the Normal variation, the middle finger is extended while the ring finger is retracted. Flush Sonics are broad and vaguely defined because they're hybrids of simpler fingerswitch-based and pass-based variations. They range between 1.0 and 2.0 rotations and have different pass-based and fingerswitch mechanics, with the only thing similar all across is the usage of four fingers (variations that use thumb are rarely called Flush Sonics), the assyemtricality of the center, and the sole possession of the pen at the extremities.

Side Sonic

The Side additive is applied to a Sonic variation when the center finger (or at least one of the those fingers) is inverted during execution. It is mostly relevant to baseline Sonic and Flush Sonic variations.
