他楽器との協奏 　Concerto with other instruments:

一台のクラシックギターが自然に出せる音量には限度があります。

私の場合はマイクとスピーカーが必要です。

そして、演奏方法としては、私はギター一本だけでなくハーモニカ、フルート、バイオリンなどの他楽器との協奏、ピアノやカラオケ音源での伴奏演奏が好きです。

プロのギタリストはギター一本だけで1000人以上の演奏会場でもマイクとスピーカーを使わず最後列の観客に音を届けられます。

There is a limit to the natural volume that a single classical guitar can produce.

In my case, I need a microphone and speakers.

And as for performance methods, I like to play not only with one guitar, but also with other instruments such as harmonica, flute, violin, etc., or with karaoke sound sources or piano accompaniment.

A professional guitarist could deliver his or her sounds to the audiences in the last row with only one guitar, without a microphone and speakers, even in a concert hall with more than 1,000 people.
