インスタコードが届いて3時間後には、これを使って自分の弾きたい曲(の譜面があれば)弾くことができるようになります。 一時は血まみれになりながらギターを練習しましたが、どうにも指先が固くならなかったため鍵盤だけにしようと思ってましたが、これで手軽に持ち運べる楽器が出来ました。非常に助かります。
It used to be so good but unfortunately it just stopped working.
This is a FANTASTIC chrome extension which shows you the chord degrees on ultimate guitar (and other sites), rather than the chords themselves. Super great for learning songs at a deeper level, wanting to study music theory, or for musicians who want to practice and learn songs with degrees so that they can more readily transpose or change instruments as needed. The fact that this comes with adjustable key detection sensitivity (since algorithms aren't perfect in detecting keys) and lets you switch between chord letters, degrees, and nashville numbers - really shows that the developer knows what they're doing and want to make a great product for us. Thank you!
chordwikiのような「弾きたい曲がここにしかない」サイトを増やして欲しい 数字の色を任意に変えさせて欲しい（というか基本黒字＋sus4は青字とかの説明も無いの？） たまに元のコードがちゃんと書かれているのに数字だと歯抜けになったりするバグがある
素晴らしいプラグイン！ ブラウザを終了すると設定値(転調感度とか)が初期化されてしまうので、覚えてくれるようになったら完璧です。
KANTAN Chord を終了させて元のtab譜表示にする方法を教えてください。 普通にtabを見たくなったときに拡張機能のアイコンを押すとKANTAN Chord が終了するような仕様になっているとありがたいと思いました。 今は、キャッシュを削除しないとtab譜を見れません。 拡張機能を削除してもtab譜表示に戻りません。
