Galway Hornpipe -- octave mandolin

This is just a trial upload and is my first attempt to create a video for my channel using my Logitech C910 webcam and software. But obviously the microphone needs to be reconfigured as many notes are distorted and some are "missing". Suggestions for improving the audio quality appreciated. This tune is the Galway Hornpipe -- named for the famous seaport on Ireland's western shore. The instrument is a 2006 Weber Absaroka octave mandolin with D'Addario J80 phosphor-bronze strings and a Wegen TF-140 pick.
