If you want to learn how to sing like Nick Lachey, here are some tips and exercises to help you get started:

1. Strengthen your chest voice: Lachey's chest voice is the foundation of his singing style. To build your own chest voice, try practicing simple major scales and arpeggios. With proper diaphragmatic support and breath control, your chest voice will eventually become stronger and more flexible. You can also try lip trills or humming on different scales and patterns to get comfortable with different vowel shapes and to get more familiar with your pitch.
2. Work on your vocal runs: Lachey's vocal runs are smooth and flowing, and he moves between notes with ease. Practice matching the runs in his songs like "What's Left of Me" and "I Can't Hate You Anymore" by listening and repeating and even slowing them down to grasp their structure. Then try incorporating them into your own singing, starting slowly and gradually increasing your speed.
3. Practice your vibrato: Lachey employs a nice vibrato in his singing, which is essentially a fluctuation in pitch that can give a warmer and softer feeling to the voice. To start working on your vibrato, try singing a sustained note and then adding a slight waver to it that feels natural to you. With practice, you can control the speed and intensity of your vibrato.
4. Build control of your middle register: Lachey's voice is characterized by powerful runs across his middle register. Focus on practicing in songs that have wide intervals in the middle register and then creating a sweet transition into the high register, which creates a smooth, rich sound to your singing.
5. Train your falsetto: Lachey seamlessly switches from his chest voice to his falsetto, which creates an ethereal sound. To build your own falsetto, try humming high notes, then gradually adding more shape and volume to it.
