I definitely haven't been playing guitar long enough to find all of the bad habits that somebody can hit. That hasn't stopped me from finding more than I thought possible though. Here's a list of the five habits that have set me back and what songs I learned that broke them.
1. Rejecting the Use of the Fourth Finger
I think this one is definitely the one that most people come across first. The reason for this is that the fourth finger is often times too weak to be able to rely on fully until you start to realize that you're helpless without it. That's why especially when introduced to high A or F sharp on the fourth string from G Major scale, many will just move their hand and use the third.
Song -Thunderstruck by AC/DC
The purpose of using this song is that the lick combination of hammer-on and pull-offs make it an easy way to build the strength needed in the fourth finger, while boosting the confidence of knowing that you will be able to impress many with this lick.
2. Rejecting the Use of Full Bar Chords
It goes without saying that compared to the traditional use of major chords like C Major or the integrated form of D5 to become a major chord, 5 and 6 string bar chords are definitely hard to get used to forming quickly. The main reason that people reject them are because of knowing that using a four string power chord usually does the trick almost exactly the same.
Song -Bouncing Off The Walls by Green Day
The verse use of power chords starting on E and A make it a simple way to build the skill of bar chords without having to shift an extreme amount.
3. Rejecting Up and Down Strokes
The little voice in my head that told me to write this was screaming about this habit as it is one I carried from the moment I started using eighth notes to very recently. Using up and down strokes was something I rejected almost immediately as a guitarist because I had trouble picking up things without having to practice them as much so I wouldn't hit the wrong strings.
Song -Know Your Enemy by Green Day
Having a guitar solo that is comprised entirely of eighth notes made this the song to break the habit because it was something that didn't take the extreme amount of coordination that I have lost through time of wasting my practicing hours.
4. Rejecting Alternate Tunings
I have a confession, I still haven't broken this one. I simply don't enjoy re-tuning my guitars for playing a few songs, especially when I always feel like I am out of tune since I'm not in standard. These are some of the few songs that I do enjoy playing in alternative tunings, although it depends from person to person.
Song(s) -This is Gospel by Panic! At The Disco in Drop D
No More Mr. Nice Guy by Alice Cooper in A:447
Round and Round by Ratt in Eb standard.
5. Playing Traditional Chords
This one was simply something where one style overtook another. I had become so accustomed to playing rock that I rarely every used those first chords I learned. Luckily a song reignited my realization that they were part of all music genres.
Song -Sleep On The Floor by The Lumineers
This song I simply loved when I heard, and that is what made me want to learn it even though it was a little far away from my style.
