One of the major issues to be found when it comes to church audio systems are unwanted echoes, reverberations and amplifications of certain frequencies caused by the large, open design of the main worship area itself. Many churches boast high ceilings with angular walls, and most of the time, these rooms are rectangular in shape. Rectangular or square, ‘boxy’ rooms have a troublesome habit of creating what are called ’standing waves’ of sound. The waves are caused by low-frequency sound bouncing from wall to wall around a room. Standing waves can radically change the way that sound is perceived, depending on the position of the listener. Church attendees in the front row may have trouble hearing certain parts of a sermon or musical piece but others scattered throughout the room may actually be assaulted by amplified low-end frequencies which drown out the whole of the sound itself.

There are a few possible solutions to this problem. The first is to install what are called bass traps. Bass traps are boxes made of wood and filled with fiberglass that act to absorb low frequency sound before it can be reflected. They accomplish this by vibrating when hit with a sound wave – unlike stiff walls, which reflect instead of vibrate. Properly placed bass traps around a church hall can be an excellent method for ensuring that the both music and speech are able to be heard with clarity by all attendees.

Alternatively, room equalization (EQ) can be employed instead of bass traps. EQ is the art of managing the balance of frequencies leaving a sound system so that they match the acoustic properties of the space where the system is placed. Equalization can be performed manually, or it can be done automatically by the device itself. When it comes to manually equalizing a church hall for a specific type of sound, sound engineers can actually enter in the size parameters of the space in front of them, as well as the approximate number of people who will be occupying that space. Even the materials that the church has been constructed out of can be taken into consideration. Once this has been entered, algorithms within the device itself can automatically adjust the sound coming out of the loudspeakers so that it is clear and bright, no matter where people are listening from. More advanced equalizers actually use microphones placed throughout a church and ‘listen’ to the sound that is being recorded. They then use a spectrum analysis which examines the frequency distribution in the room and automatically adjust the EQ to compensate for any trouble spots.

God has given us talents to sing his praises and playing guitar for the church is one of the greatest ways to glorify God. There are several well known duets, solo artists and even bands that go from church to church playing gospel music for God’s glory. You too can learn guitar for god praising.

I’ve had the honor of playing in a band while singing in a few churches and I know there’s no greater feeling than to be blessed with the knowledge that you had blessed others with your music. Whether you’re an experienced guitarist or you’re just starting out, God will inspire you to play guitar for worship. By asking Jesus Christ to come into your heart, you would have made a commitment to bless others. This would make one start to appreciate the life that Jesus Christ sacrificed himself for in a different light.

In modern days, several churches have their own sounds systems built in with microphones and amplifiers. The acoustics are pretty amazing in the sanctuary of the church and provide a rich and clear sound. One important tip is that you should choose the most appropriate songs that will bless the majority of people in your congregation. Another tip is to make sure you pick songs you will be the comfortable playing and singing at the same time.

Practice and learn everything you can about playing the guitar and the different major guitar chords. You can play several church gospel hymns with only three guitar chords and a few gospel songs with as little as two guitar chords. Once you learned the basic chord progressions of songs, you should then practice those songs over and over to make them perfect. Finally, be sure to record yourself and listen to the recordings for any improvements that need to be made. This will help you polish up your skills in playing worship guitar. Have lots of fun while you learn guitar for praise!
