If you're looking to learn singing like Sia, it's important to focus on vocal power, control, and range. You'll also want to develop your own unique style, much like Sia has developed hers. One of Sia's standout vocal techniques is her use of belting, which is a way of singing where you push your voice to its limits, producing a powerful, expressive sound.

To achieve this, you'll want to focus on building your breath control and expanding your vocal range. You can do this by regularly practicing breathing and warm-up exercises such as the Farinelli Breathing and the 3 Minute Warm Up tools provided by Singing Carrots. It's also important to focus on strengthening your chest voice, which is the voice you speak in, by using targeted exercises such as the Singing Comfort Zone tool.

In addition to these foundational techniques, you'll want to develop your articulation and pronunciation skills, so you can clearly express yourself through your singing, thus making your music more engaging. Use Singing Carrots' Vocal Pitch Monitor to precisely monitor your accuracy and how well you are projecting your voice.

When it comes to singing like Sia, it's also important to work on developing your own unique style. Sia has a reputation for creating rich, complex harmonies and a raw, emotive quality in her vocals. You can experiment with different vocal techniques such as the vibrato technique and twang technique using Singing Carrots' video exercises linked above.

Applying Sia's techniques to specific songs is another great way to learn. You can try singing her famous tracks like "Titanium," "Cheap Thrills," or "Chandelier," choosing one that fits your vocal range while also challenging you to push your limits. You can use Singing Carrots' song search tool to find more songs within your range.

Overall, if you're looking to learn singing like Sia, it's all about building on strong techniques, and finding your unique, powerful voice through practice and experimentation.
