As many other people, I wanted to learn how to play the guitar for years and finally made the decision to invest time regularly in order to get to a decent level. I am using a quality acoustic guitar and started practicing some essential stuff, like basic chords, strumming patterns and little things that are fun. I should also mention that I am not taking any lessons, so I am using only the internet as learning material.
Although I do not practice as often as I'd like, I feel like I am making some progress with my left hand, regarding chord changes, speed, and overall accuracy. However, I've noticed that my right hand is very inconsistent when strumming. Even on a simple rhythm of only down strums, the "power" that I use to hit the strings varies a lot, such that some strums are almost silent and some are very loud. If I try some simple patterns using up strums, things get even worse. I know that I'm supposed to hit only the thinnest strings, but sometimes I miss the up strum completely (don't hit any strings). If sometimes I am lucky, I am only able to hold the rhythm for a few bars, then I start making mistakes. Even if I'm doing a decent job with my left hand, the right hand technique completely lets me down and I feel like I'm stuck.
From what I've seen online, basic strumming ability is kind of assumed, and I do not know what to practice. Trying to keep the strums slow feels unnatural, and I often end up doing random movements to test what sounds best, but I don't want to pick up bad habits.
If anybody could suggest some ideas/exercises or anything in order to progress, it would be appreciated!
