Her voice is recognisable and she has an interesting ability to manipulate her voice to different genres of music but at the same time maintain her instantly recognisable voice. Her strongest range is from G3-C5, where her midrange lies.
Britney Spears has a very nasal voice and her voice quality gets thinner as she goes higher, starting from C#5. She heavily relies on lip syncing and autotune owing to the fact that smoking has damaged her voice aggravated a bit by aging as well. Her notes below G3 are no longer as well-supported as before.
