Future bass

Future bass is a style of electronic dance music which developed in the 2010s that mixes elements of dubstep and trap with warmer, less abrasive rhythms. The genre was pioneered by producers such as Rustie, Hudson Mohawke, Lido, San Holo and Cashmere Cat, and it was popularised in the mid to late-2010s by artists such as Flume, Martin Garrix, Illenium, Louis the Child and Mura Masa. 2016 was seen as the breakout year for the genre.

History
The genre was pioneered by Scottish producers Rustie and Hudson Mohawke and American producer RL Grime, who began producing future bass tracks in 2010. One of the first popularity-fueling releases in the genre was Rustie's album Glass Swords, released in 2011. Later, in 2013, the Flume remix of Disclosure's song "You & Me" brought the genre into the mainstream, and through the mid-2010s future bass became popular in the United Kingdom, United States, Japan, China, Korea and Australia.

Characteristics
The sound waves are often modulated using automation or low-frequency oscillation controlling the cutoff of an audio filter (typically a low- or high-pass filter), or the wave's amplitude, to adjust the waveform (to create a ‘wobbly’ effect on its parameters). In addition, it is common to utilize a somewhat "twinkly"-sounding gradual rise in pitch during "risers" (gradual pre-drop buildups of white noise), and arpeggio chords, vocal chops, or vocoders.

The BPM of future bass is often set between 130BPM to 175BPM, and the tracks often use a 4/4 time signature. However, a song does not have to follow those criteria to be considered "future bass".

Kawaii future bass
Kawaii future bass (also known simply as kawaii bass) is a subgenre of future bass, known for its happy and cute timbre and strong Japanese pop culture influences. Often, chiptune sounds, soft square waves, samples from anime or video games, percussion instruments, and door and bed squeaks are incorporated into such songs. Snail's House and other producers have produced tracks of this subgenre, with the former being credited as the genre pioneer after releasing the extended play Kirara in 2015.

J-future core
J-future core (also known simply as Future core), refers to hardcore styles mixed with melodic content and the characteristic sound design of future bass. Its name comes from the "FÜGENE" compilation album on SoundCloud in the first half of 2017. Often, chiptune sounds, active square waves, edited vocals, samples from future bass and Hardcore (electronic dance music genre), percussion instruments, make the genre sounds more like a Future products. The compilation led some music producers from Japan to recognize it as a new musical genre.
