You're not going to mutate significantly. In time, you'll learn to place your fingers more precisely.

In some cases, this might mean placing the finger to one side rather than in the middle, because you might not need to worry about fouling the string on one side (e.g. if you're fretting it higher)

Another important thing is to put your fingers close to the fret you're playing. This allows you to press down less hard, which makes the fingers 'squish' less.

You'll also get better at feeling and hearing when you're accidentally muting a string, and be able to correct faster with less conscious thought - so your mistakes will matter less.

You'll also anticipate where you need to put your fingers further into the future, which will help you make fewer mistakes.

Sometimes I even have to 'cheat' a little by bending one string a little away from a potentially interfering finger! It takes a little time to get the co-ordination to do this.

Having said all that, you may well find that your fingers harden up a little, which may help you press a little less hard (which again avoids some of the squishing). It's probably only a tiny effect, but all these factors add up.

Aby dodać do doskonałych odpowiedzi Todda i Topo - dodam swój głos, aby zapewnić, że z biegiem czasu będzie lepiej. Właściwie mam krótkie, grube palce i nauczyłem się to kompensować.

Oprócz ustawienia palca i kąta natarcia, inną rzeczą, którą możesz potrzebować dostosować, jest położenie kciuka na karku. Uważam, że aby dokładnie zagrać, pewne akordy bez wyciszania strun Nieustannie poprawiam położenie kciuka na karku. Każda formacja akordowa ma swoją własną pozycję kciuka. W końcu bardzo intuicyjne stanie się uwzględnienie pozycji kciuka dla niektórych akordów jako części pozycji palca w tej formacji.

Na przykład wiem, że kiedy gram otwarty akord E-dur, muszę przesunąć kciuk w stronę wysokich tonów na karku, aby moje palce były ustawione prostopadle do podstrunnicy. Podczas gdy moje palce formują się w prawidłowej pozycji w powietrzu - mój nadgarstek obraca się, aby kciuk mógł przesunąć się bliżej górnej części szyi. Kiedy gram otwarty akord D-dur, mój kciuk jest skierowany prosto w górę, a czubek kciuka nie znajduje się nawet na karku. Akord C sprawia, że ​​mój kciuk jest bardziej równoległy do ​​szyjki gitary.

Wypróbuj różne pozycje kciuków i ich orientację w przypadku akordów, które sprawiają Ci kłopoty, a może się okazać, że zmiana pozycji lub kąta kciuka może ułatwić ustawienie palców tam, gdzie powinny być .

Powodzenia.

It will change, but not because your fingers will change, because you'll get better at perfect finger placement. First, your minor finger corrections will come more and more quickly. Then, you'll start to put your fingers in the right place in the first place.

With daily practice, you should have much improved finger placement after 1-2 years. You don't have to wait that long to learn interesting techniques or challenging songs, it just means that at that time your playing will start to sound pretty good in a subtle way.

I'm skeptical about writing this as a full answer - this is mostly an addition to the excellent answers others have already posted.

As a young and amateur guitarist I had the same issues (obviously). What helped was... cutting my fingernails short.

With shorter fingernails I was able to place my fingers at a better angle without having the nail hit the fret board, and this also means less "squishing" and less accidental muting.

Since I'm a male having short fingernails doesn't concern me at all. That said, I have no idea how do female guitarists manage it (if they want to keep more "feminine" hands). ;)

Once I started playing banjo a great deal, my fingertips developed callouses that were significantly harder than my fingertips were before I started playing. With these callouses, my fingertips don't flatten out as much when pressing against a string. This does help to keep from muting adjacent strings.

This is not the only thing that helped. Short fingernails (as mentioned by @Shaamaan) helped. Good finger placement helped. Practice was the key to developing all of these things.
