中型以上のヘッドホン奨励♪
テンポ180位の練習。
スローパターンから高速アップテンポツーバス連打までひたすら20分以上演奏し続けました。

前半はオカズほとんど無しでツーバス連打メイン。
後半はアドリブオカズ多彩な練習。

If they're a medium size and a large headphone, everything is heard.

A loudspeaker of a cellular phone isn't heard tightly.

The tempo is 180.

It was played from the slow pattern to the fast pattern.

I kept playing for more than 20 minutes by practice of this tempo 180.
