The sound waves are often modulated using automationorlow-frequency oscillation controlling the cutoff of an audio filter (typically a low-orhigh-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.[1]
The BPM of future bass is often set between 130BPM to 175BPM,[12] 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 (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 animeorvideo 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,[13] with the former being credited as the genre pioneer after releasing the extended play Kirara in 2015.[14]
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.[15]Its name comes from the『FÜGENE』compilation album on SoundCloud in the first half of 2017.[16]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.[17]
