Im a beginner guitar player about 3 weeks in and im going through the chord section in guitar fundamentals at the moment. Ive already developed some calluses or slightly tougher more firm skin on my finger tips. I find that when im holding down the chords and practicing the chord changes the strings shape gets indented into my fingers making a groove. As this happens I have to press down even harder so my strings dont buzz when im strumming them. I was wondering if maybe I am pressing down to hard on the strings initially or if maybe the calluses on my fingers just arent developed enough yet? Its mildly frustrating when Im pressing down really hard and still cant produce good tone. Any feedback would be appreciated. Thank you.
