Ranking singers based on vocal technique can be quite subjective, as it often depends on personal preference and the specific aspects of vocal performance one values. However, I can provide a tier-based ranking of the singers you mentioned based on their vocal technique and overall artistry as of my last knowledge update.
S Tier:
- Halle Bailey: Known for her precise vocal control, agility, and broad vocal range. Her performances often showcase exceptional technique and emotional delivery.
A Tier:
- Coco Jones: Highly regarded for her powerful vocals and strong technique. She demonstrates a solid control over her voice and versatility in her performances.
- Mariah the Scientist: Known for her unique vocal color and emotive singing style, she combines technique with a captivating delivery.
B Tier:
- Kehlani: Strong technical skills and emotional depth in her singing, though sometimes focuses more on style and vibe.
- Summer Walker: Has a smooth, soulful voice with a relaxed vocal style, but her technical prowess varies in live performances.
C Tier:
- Tate McRae: Known more for her songwriting and pop appeal, she has a solid voice but may lack the technical refinement of others in higher tiers.
- Dua Lipa: While she has a distinctive vocal style and excellent stage presence, her technique is more pop-oriented and less focused on vocal intricacies.
D Tier:
- Doechii: Emerging artist with a unique style and sound, but her vocal technique is still developing in comparison to more seasoned artists.
F- Tier:
- Manon from Katseye: As an emerging artist or lesser-known entity, it's hard to gauge her vocal technique relative to the others in this list if she hasn't extensively showcased her technical abilities in a widely recognized format.
Please note that opinions about vocal technique can differ widely, and artists' rankings can fluctuate based on personal preferences, live performances, and new music releases.
