Going to throw my "journey" out. Incoming wall-o-text:
I started aged 16 or 17 (end of the 80s so take it from there).
I started on electric. A rubbish electric that very nearly put me off playing for life, and I upgraded as soon as possible.
I had lessons for about a year, learning a few scales & songs. No real theory.
Started jamming with friends. We were terrible.
At 18 I went to university. 1st 2 years I put a huge amount of time into guitar, basically when I wasn't doing anything else.
3rd year uni I picked up my 1st really good guitar (I still own it - a Jackson Professional).
4th year uni I joined a band. That really upped my game. Bassist was a slavedriver and we rehearsed 3 times a week. We ended up tighter than satan's balls and actually reasonably good. Mix of covers (Metallica, Therapy?, Primus, Megadeth, Pantera, Anthrax & some others) and originals, playing mostly originals at shows.
Moved to London in 95, in part to get away from the fantastic amount of chemistry that my peer group was up to. Spent 2 years sat in flat working on picking technique.
Girlfriend happened in 97, kinda stopped playing.
Restarted in 2000. Formed band with friends in 2001. Played weird/ugly thrash/death metal loudly at people.
Got quite good again, then all fell out with each other in about 2005.
Carried on bumbling around with some previous members, never really got going properly again but we played a bunch of shows over the years. Style went more prog/sludge/doom.
Turned into a guitar slag around here.
I got into modular synths & similar silly boxes. I have no idea what I'm doing with modular synths.
Lost about 9 months somewhere around here due to nerve problems in left arm. I had to partially re-learn how to use my fretting hand after this. Do not recommend.
Joined trip-hop band on keys in about 2012. I don't know what I'm doing on keys. Band folded after all fell out with each other.
Joined another band on bass in about 2013. They all loved The Melvins. I don't know what I'm doing on bass and don't listen to The Melvins. Seemed to start fairly well, all things considered.
Dregs of original band called it quits in 2016. Wasn't going anywhere.
Band I played bass in folded in early 2018 due to lack of interest and/or excessive drug abuse by various parties (not me).
Noodled at home ever since. I miss the music side of being in a band - and playing live - but not dealing with musicians!
Hints/tips/asides/thoughts/etc:
- Buy a guitar that you want to play - if you don't want to pick it up you won't play it.
- Cheap guitars now are actually pretty damn good. Try before you buy is vital, though. It needs to "talk" to you.
- Learning classical is hard & difficult to play. It will give you really good technique.
- Learning acoustic is (relatively) simpler & easier to play. You learn good technique.
- Learning electric is also simpler and even easier to play. My technique is still atrocious as you can get away with murder (relatively).
- I personally found lessons useful as they are structured, with homework. I am fantastically unstructured (ADHD) so needed that. YMMV.
- You will be utterly rubbish for years. This does not matter.
- You will need to put time into playing.
- How you structure your play time is less important than actually having play time.
- If you go electric buy a little practice amp. Playing through an interface into a computer throws in latency. You don't want this until you learn how to compensate. IMO. Personally I find it a pain, and avoid direct recording.
- I regret not learning on acoustic (not so much classical, screw that) as I would have better basic mechanical skills even now.
- Playing with other people will make you improve faster then you can imagine.
- There are kids 1/3 my age doing ridiculous things on YouTube. Don't let it faze you.
- Play along with stuff. From when I was taught my first scale I jammed along with ZZ Top albums. Blues is great, as with basic scales you can sound "musical" really quickly, and it also teaches note choice. YMMV with the music choice but you can only really learn how music feels by playing it.
That's pretty much all I can think of right now. I'm supposed to be working so... erm.....
Oh, I also grew up just outside Portsmouth. Can't recommend any resources as haven't lived there for decades (although my bro used to teach guitar - classical, electric, acoustic - but he moved away).
