The best way is with a teacher, so I'm confused when you mentioned being disabled and lessons not working for you in the same sentence. How'd you learn the trumpet? There are some okay ways to teach yourself, but nothing beats a qualified teacher. Why so averse?
Lots of things beats a qualified teacher.
Nothing worse than seeing people ask for advice, people who state they can't use a teacher at the moment for whatever reason, to have someone come along and question them. It happens all the time on this forum and in my opinion is this forums worst trait.
Personally I wish the site owner and mods would introduce a rule banning posts like yours when people have stressed they want to teach themselves.
Not everyone fits into the same pattern of learning as others do, some may find they need a teacher to learn, others may have a teacher now and wish they had gone this route many years previous.
But there's also the others. Those intelligent people who don't thrive well in a classroom environment but end up as math geniuses etc.
Many people need teachers to teach them math, physics, guitar, piano or whatever. Many many others do just as well (and often better) without.
There's also far far far too many people who are qualified at teaching their particular field as far as their qualifications and training goes, who should never ever be let anywhere near a student of any age as while these teachers have the head knowledge, they are unable to relate to their students in any way shape or form.
When I think back 35 years to when I was at school, I had a load of different teachers for many different subjects, but I could count the ones that were really good teachers on one hand if I had two fingers missing.
That all applies to a fit and well student with loads of study time spare, able to schedule study times every day, and have the financial means of paying for a teacher.
As soon as you bring illness (and many other things like wanting to be able to afford food regularly) into the equation, saying someone should get a teacher, and sort of implying you don't know why being disabled should affect that decision, well it shows me you haven't much experience as to how different illnesses can affect different people.
I'm ill. 15 years ago I was earning £42k, for the last 12 years I haven't been able to work and the hospital specialists won't let me even consider part time work. Last year I received £5200 in state benefits, £100 a week, and that's gone up by a little each year.
My wife works, we are financially fine but we don't have much spare money at all due to me not earning. She recently treated me to a Korg Kronos 88 which wasn't cheap, but she knows that I hardly leave the house, music is something I enjoy, and she is happy for the family to go without a holiday for another few years for me to have such a nice treat.
But even if I actually wanted a teacher, we couldn't afford one. But it's far more complicated than that.
Every one hour I'm up, I have to take a 15 min rest.
Watching TV, reading a book, listening to an audio book, playing my keyboard, being in a room sitting down talking to someone, none of that counts as rest. So if I'm watching a film on tv, I have to pause it and go into the other room, put on some chill out music and sit in my armchair, arms and legs relaxed, eyes closed.
If I went to see a teacher, the time putting on my shoes etc isn't rest, the walk to the car isn't rest, neither is the journey in the car. Then there's the lesson, then there's the drive home.
Chances are I wouldn't end up back in my armchair relaxing within the hour and if I don't, then the next day or two I will spend mostly asleep and won't have the energy to play my keyboard at all.
But it's worse than that, the 15 min rest every hour is for when I'm doing very little at home. As soon as going out is put into the equation or having to meet people at a certain time, that's a different thing altogether.
This morning I had a doctors appointment where all I had to do was have my blood pressure taken both standing and sitting, squeeze a handgrip three times to measure how hard I can grip things, then blow into a device three times to measure my lung capacity.
My appointment was at 9am and I was done by 9:15. She stressed she wanted me to go home and do virtually nothing for the rest of the day as that 15 mins (along with having to get there) would have been too much for me.
All that aside, often I sleep for hours in the day time, there's never two identical times I can play, I might feel up to practising at 10 am tomorrow, 3pm the next day, not have the energy to practice at all the next, and happily be able to practice/play anytime the following day, just pausing for my rests every hour.
So if I wanted a teacher, I would have to find one that could either come to me, was 15 mins or less drive away, was dirt cheap, and I can phone up and say I will be well enough to come right now, but I can't guarantee if I will be well enough in two hours time, yet alone a fixed time and date next week.
What's more, if you knocked on my front door and I answered it, you would presume I was a normal healthy man.
Many people have many reasons they can't have teachers, people with physical or mental (or both) disabilities where they are fighting with pain, breathing, headaches, not being able to concentrate for periods of time, etc, none of these can book an appointment in advance as they dont know how well they will be on the day.
Then you have those where the stress of meeting with a teacher is simply too much (hard to understand if your well, but can be very very draining if your not).
And many of us choose a musical outlet.
13 years ago I could walk miles, swam regularly, went to the gym, had a big garden I enjoyed working on etc etc etc. In the past few years I've just existed really, three months go by and I struggle to find something I've actually done except for watching tv or browsing the web (can't concentrate on books anymore, have joined audible as if I didn't listen to them, that would be another pleasure lost).
So I buy a cheap 2nd hand keyboard a year or so ago, and I finally have something I enjoy that isn't tv or computer (I used to have many synths all hooked up to my Atari computer years ago before I got ill) and my wife sees how much I'm enjoying it and how I have a sort of purpose/outlet again. So she buys me some computer synths (Native Instruments Komplete), my daughters at Uni and my wife gave her the money to buy me the educational version of Cubase for my PC, and this year she treats me to my Kronos that I've been going on about since it was mentioned early last year.
And I'm very very happy.
I want to learn to play better, I've got an online course recommended by someone on this board (play piano today) and I'm enjoying myself having fun and learning well in my opinion.
With the wealth of YouTube vids etc, there's plenty of info out there for the person like me that wants to learn themselves.
Thing is, I'm usually very very reluctant to ask questions etc on this board as I know someone will simply respond " you need a teacher"
And absolutely no one should have to explain themselves to you like I have above to justify themselves for your benefit when they say a teacher is out of the question.
If someone says they cant have a teacher, who are you to judge their reasonings and question them when they say this?
I only described my personal situation here to show you how unfair it is for you and others to keep saying this.
Please stop.
Best
