CORE 

Referring to the 65th track in the Undertale OST, CORE is a two-minute forty-six-second track composed by Toby Fox in the FL Studio 10 DAW (Digital Audio Workstation). CORE has a consistent BPM of 140 and is in the key of C sharp. It plays during "The CORE" sub-section of Hotland in the hit 2015 indie game Undertale, made by American game developers Toby Fox and Temmie Chang, and is one of the more intense tracks in the OST.

CORE is mainly built off of melodies from Another Medium, the 51st track in the OST, and the main theme for Hotland, and Death By Glamour, the 68th track in the OST, and the boss theme of Mettaton EX, and CORE repurposes those melodies via VERY smart sound selection in the SGM soundfont and sound designing on the the 3x Oscillator to elevate it to one of-- if not-- the best area theme in Undertale.

What the fuck is the CORE kick
