If you want to learn how to sing like Gesaffelstein and The Weeknd, you need to learn how to manage your breathing and voice. A good singing technique will allow you to emulate Gesaffelstein's deep, aggressive voice and The Weeknd's smooth, falsetto range.

To train your vocal cords, start by taking a vocal range test. When you know your vocal range, follow the appropriate pitch training exercises for your voice type. Be sure to focus on breathing and proper posture when singing, as breathing is a vital part of singing and posture can give you the support you need to sing properly.

To emulate Gesaffelstein's dark and aggressive voice, focus on using your chest voice and diaphragm when singing. Gesaffelstein's songs usually feature low notes, so practice singing in your lower range. Take some time every day to warm up your voice. Try humming, doing breathing exercises, or singing a low note repeatedly until you feel comfortable.

The Weeknd's music is characterized by his use of falsetto and a smooth, R&B vocal style. To sing like The Weeknd, focus on using your head voice instead of your chest voice. This allows you to hit higher notes without straining your vocal cords. Warm up by practicing your transitions from chest to head and back again.
