Church music

Preludes, offertories, postludes seem to some people basic background music that we hear in stores and many public places.   Unfortunately, or perhaps fortunately, it’s not that way for me.   I’m one of those rare people who begin to hum or sing along, yes, even in public.  
My husband sometimes found it embarrassing to have his wife publicly, sing along to the background music.  Yes, I was the one singing at the restaurant or Walgreens.   It caused us to only shop in places together without music piped in or him calling ahead and asking for the music to be turned down so low that it could not easily be heard around other people’s noise.
Yet in his embarrassment, he told me he was jealous of my being able to find music where it is usually hidden.
So, why listen to preludes, offertories, and postludes?
A prelude is to begin the worship service is a time to privately converse with God.   This can be in private meditative silence, prayer, thankfulness, praise, or whatever speaks to you through your relationship with God.  
For me, the offertory is a gift.  This gift is usually some melodic tune that I believe opens up hearts to the Holy Spirit through the gift of music.   That is why people don’t talk during that time and I just don’t stop whenever the ushers are finished collecting the monetary gifts.
The postlude is usually in praise.   The congregation does not have to leave, but can reflect on the service, their blessing, the message without words into their lives.   Many times people in our church choose to continue to sit to listen.  For me, that is a peaceful summary of the service through music.
To write this has been difficult for me.  I frequently write for book reviews and events, where the focus is on something outside of myself.
This is inside myself.
Sometimes when I play a familiar tune with words, many people know, I find myself overtaken with a strange feeling.  It feels as if I am the instrument, not the piano or organ I am playing at the time.   There is a feeling inside that seems to swell and take over the actual playing.  At the time, I am singing in my head, the words of the song, oftentimes repeating the same significant words over and over even though the hymn is not written that way.
My husband once commented that I actually look different when that happens.  It feels like something much stronger and passionate is expressing itself and strictly using me to communicate.
No, it is not possession. It can’t be because the peace immediately afterwards doesn’t feel worldly.
At those times, I feel as if the Holy Spirit is communicating through me to others in a language that cannot be described in words.
My husband also observed the other worshippers and also commented afterwards that something happened.  He just didn’t know what to call it.
This is a time of one-ness.   Soul talking to soul.   What is it saying?
It seems to be tunneling a message deep inside to others who listen.
God moves in mysterious ways.   Listen.
