Traditional singers mainly pitched their voice around where they spoke (age and physical condition allowing) - their physically 'natural' voice)
THe easiest way to develop your voice for traditional singing is to find your natural voice and learn to control and extend it
"Both men and women have head and chest voices"
Hi Jack
Men's 'head voice' tends to be falsetto
Head voice (unless it is 'natural' to yo) takes twice as much air to produce and can make singing long lines a problem
In women, it tends to produce the dreaded 'gear change' - a tonal shift from head to chest aaand vice versa, which can sound odd if not controlled
