Keep your throat and neck muscles relaxed even when singing high notes and low notes. Some singers tilt their head up high when singing high notes and down when singing low notes. "The high notes are on the ceiling and the low notes are on the floor". This will also cause future limits on your vocal range. For more lessons : https://chat.whatsapp.com/JWqVkdz3U3tFkLzS5Ksz9X
