I am merely a musician of mediocre talent who creates because I dearly love music of all genre, save maybe a small few sub genres, but my taste in music is vast. At the age of 5, my uncle taught me three chords on the guitar and it lit a fire that's been burning for 65 years. I never pursued a professional career, tho I've sat in with tons of people, and thoroughly love an impromptu jam on some nondescript street corner of town with other musicians. I always thought that doing it for a living would surely sully my love of the melodic muse.
To make it big today you have to have these words in your track, these rhythms, has to be this long, et al. It's all so very regimented, and that is in direct opposition to my creed of 'play what's in your heart'. So, I am probably not the guy to give professional advice. It's just nice to meet another musician on Lemmy.
I too am a guitarist and I have quite a collection. A lot of old wood like Gibson J-45s and Martins. My uncle made sure that I received his entire collection when he passed. I haven't posted any of my tracks here on Lemmy, tho my SoundCloud link is in my profile.
