Frank Sinatra was known for his smooth and natural vocal style, often described as having a lack of "vibrato" or excessive vibrational quality in his tone. There are several factors that contribute to this unique quality in his voice:
Technique: Sinatra was a highly skilled vocalist and had excellent control over his voice. He had a deep understanding of breath support, pitch control, and phrasing, which allowed him to maintain a consistent and steady tone. He used a relaxed yet focused approach to singing, which contributed to the smoothness in his voice.
Articulation: Sinatra paid careful attention to his diction and articulation. He enunciated each word clearly and precisely, allowing his voice to glide effortlessly through the lyrics. This attention to detail helped him create a natural and legato style of singing without any excessive vocal fluctuations.
Phrasing: Sinatra had a remarkable sense of phrasing. He had a knack for interpreting songs and conveying emotions through his delivery. He used subtle variations in timing, dynamics, and emphasis to give his performances a sense of ease and authenticity. This approach contributed to the overall naturalness of his voice.
Vocal Quality: Sinatra had a naturally smooth and rich vocal quality. His voice had a pleasing timbre, with a balanced mix of warmth and brightness. This inherent quality in his voice, combined with his technical expertise and artistic choices, allowed him to create a signature style that was characterized by its naturalness.
It's important to note that while Sinatra's voice may sound devoid of excessive vibrato, he did use vibrato sparingly and purposefully when appropriate for certain songs or emotional moments. However, his ability to control and modulate vibrato added to the overall naturalness and control in his singing.
