The vocalization is the action of muscle movements, including the vocal cords, and the vocal cords are composed of soft tissues.
Therefore, vocalization is really similar to and could be categorized as a sport.
Although the amount of time for practicing a sport varies from each person. The ideal time to vocalize is 45 minutes straight, after that take a break and rest for 15 minutes, then start vocalizing again for 45 minutes.
I tested how long is the best amount of time to vocalize, using the four different times and methods listed below.
1.Singing for 15 minutes and then taking a rest for 15 minutes (Repeated 12 times)
2.Singing for 45 minutes and then taking a rest for 15 minutes (Repeated 6 times)
3.Singing for 90 minutes and then taking a rest for 30 minutes (Repeated 3 times)
4.Singing for 150 minutes and then taking a rest for 30 minutes (Repeated 2 times)
6 hours later, 1 and 2 can display the same voice quality as before singing but 3 and 4 displayed a hoarse voice.
Especially 4. Which after the test, continued to have problems with the voice for few days.
As a result, I have concluded 2 is the best and ideal time for practicing vocalizing.
Is a quiet voice or a loud voice perceived as a good voice by listeners? I ran an experiment which analyzed 10 people. Each listened to one song twice and then answered which one had better sound, as well as which was more enjoyable. The song used for this experiment was, “Feel This Moment,” by Pit Bull.
This song is really suitable as a reference, because it has a wide range and so many kinds of rhythmic patterns.
I asked all my test participants which song version, the first or second, had better sound. This was asked after everybody listened the same song twice, and all 10 test subjects answered that the second one was better.
Honestly, the only different between the first and the second song is that the second song version is louder. The second song was increased in volume, 5% more than the first song.
Even if you use the same music and the same music player, you can just hear the instruments and vocals of the music better at a higher volume. Also according to the test subjects it is more enjoyable with a louder volume, instead of soft and quiet volume.
This is the same concept as with vocalization. If you let out a slightly louder voice than usual, your voice sounds better. I would like you to you try this with daily conversation or singing.
Note1:I changed the volume by %, using MA6700 (Mcintosh) but not dB.
