Musical Challenges

I had another new musical challenge today.  I was more nervous this morning than I have been in quite some time.  I wish I knew what it sounded like to the congregation.  For the music I did, there was no accompaniment to be found...so I sang a capella.  Actually, I had the recording playing on my tablet with my hands-free set in my right ear and the lead sheet in front of me for the words.  So, really, I was singing along while the congregation heard only my voice.  I don't know if it was because I had to rely on the technology or because I knew there was no instrument to help mask a mistake, but I was I truly nervous.  I have sung a capella before both alone and in groups.  The song was "Surely Your Salvation is Coming" which is verbatim NKJV of Isaiah 62.  It is beautiful.  I only sang verses 1-5, though because that's all the reading was this morning.  You can find it here if you would like to check it out (the artist's singing of course, not mine): http://www.scripturesongsforworship.com/2012/06/isaiah-62-surely-your-salvation-is.html.  Despite the nerves, I'm glad I was able to do it.  The song was pretty, the modus operandi a first for me, and it was a new challenge which is always good to have once in a while.
