"Classical guitarists can play without using nails, but they should be aware that in doing so they are sacrificing certain possibilities of tone color and projection-----all of which affect interpretation and musical presentation. The nail, when used alone or with the flesh of the fingertip, adds clarity to articulation and aids in projection, from the softest to the loudest passages. For example, a pianissimo passage played only with the flesh will sound fuzzy and indistinct, yet the same dynamic shaped with the nail projects beautifully, even in a large hall"
吉他弹奏可以不用指甲，但是如果这么做，代价是牺牲音色和失去对音乐的解释和表现。用指尖上的指甲和指肉能够弹出更具表现的声音，从最柔和到最强烈。比如说，闷音奏法如果光用指肉来弹会显得模糊不清，用指甲的话就好得多，甚至在音乐厅这样的大空间里也能听清楚。
