Wherever I am, I initially transcribe Rhythmic things that catch my attention, Mentally then on hand writing. Shallow and silly as it seems, they are all Musical to me. I try to install them in my Mind where I build my Musical Database.
I was just checking on my son who just turned 1 month a few days ago. In his room, I could hear the machine noise sounds coming from the Aircon/Fan. He was sleeping. I came closer to him and heard something new. So I used my Voice Memo App to record it.
