Psychoacoustic versus worship.

I'm not sure about this, really!

Music was 1st invented for spiritual worship purposes. It means it's having the ability to bring human's mind into another level of realm. (Christians believe that 1st musician was Lucifer, who became fallen angel when he started to worship himself instead of God with music). The history tells that music was developed only for spiritual purposes before it became an "art" for the society. After that, music was developed even more rapidly by the "world musician", its purpose was shifted from spiritual to entertainment.

So, we bring back this question: does music really affects one's mind? Can it bring a person to another realm and affect the emotion etc? Reality tells us that it does, e.g. Mozart effects causes the spatial intelligence to increase temporarily, Death metal music may bring people to think about despair, depress or emo.

Can we play or arrange something to bring christians to worship more deeply (mentally)? Will the way the singer sing-whether have emotion or not- bring the worshiper to different "place"?

Oxford university came out with a research recently, it says that we can hear shapes and taste colour.. What the heck is this? This is non other than the power of other senses (other than sight) on predicting an object's characteristic. Have you heard someone said "Marshall amplifier have a more rounded sound" or "when playing classical guitar, one should get the round sound and not the oval one". One tends to relate a lower frequency sound (lower tone) to rounded object and higher frequency (high tone) to sharp object. Does this effect mean anything to the music arranger when arranging a complex sequence of notes and harmonics? What will we "see" and where it'll bring us to? Can this be applied to spiritual purposes or was music first invented for this purpose?

Of course, worship leader must have a pure heart in worshipping God and he shall lead the members in the house to worship. But, what is the purpose of music? For a same worship leader, can he leads even better when there is an expert music team behind? Or when there is a team of psychoacoustic experts supporting him..?

psychoacoustic---psycho=mind, acoustic=sound. Is this the relationship?

Wanna buy a guitar..

What guitar should i buy, or should you buy? These are from my experience..

1. Wood of the guitar. Different wood gives you different sound, e.g. spruce top gives a very bright sound while koa top gives a relatively mellow sound. Rosewood back gives a bassy sound and maple back gives a more thin sound. It depends on what sound you like.

What about the quality of the wood? Let's say if you have a normal spruce and grade A spruce, the only difference is the stability of the wood. For the grade A wood, it's already seasoned and the sound quality is assured. But, for a non seasoned wood, chances are, it turns out to be very nice or very bad, some (those that are not completely dry) may even bend, which is very very bad..

Another thing, some say the different wood looked differently, e.g. some has more packed pattern, some loose. The packed one is sold more expensive, because of it's "artistic" look, not the sound quality..

2. The bracing. Even from same wood, different manufacturers have different style of bracing design. It affects the sound quality also. Hence, you'll have to try out few guitars so that you can get the sound that you prefer. Personally, i prefer Martin guitars than Taylor guitars.

3. The action. Even how good the sound is, if the touch is very bad (very hard to play), it's useless. I'd tried some handmade guitars before, although the sound is not bad, the strings are way too high from the fret, hence it's akward to play fast. The neck thickness, the buzzing of strings, etc.. these have to be considered.

4. Then, you have to check check very carefully the accuracy of tone each strings at each bar. make sure that the tone (especially after 12th bar) is still consistently in tune.

5. The value of the guitar. I'd been thinking of this question for some time. Good instrument will have their value increase over time. e.g. you bought a Selmer saxophone at 50's, now the price is almost 30 times the price last time.. But if you buy a kapok guitar, do you think you can even sell the guitar? This is the different, hence buying good guitars is another kind of investment, provided you really know how to take care of it..

These are what i know so far. I heard people say that hand made guitar's sound quality will increased by time, but machine made one won't.. I doubt on this. Also, don't be cheated by the price and think that price higher, sound better.. it's not that case. Some price are meant for the outside look only, not the sound nor feel.. E.g. standard taylor has standard price. Those limited edition one will have the more or less same sound, but the design varies a lot..
