17平均律

17平均律はオクターブを均等な17パートに分割したものであり、各ステップは70.588セントである。13平均律に次ぎ19平均律の前となる、7番目の素数平均律である。

# 17平均律の音程と近似値

各周波数比の大きさが16以内で表現される純正音程は以下のようになる。これはedjirulerを用いて、[number of equal divisions=17, interval of equivalence=2, integer limit=16, threshold of JI pitch inclusion=0.25]というパラメータで生成したものである。「The “neighborhood” of JI」の一覧はこちら（huygens-fokker）を参照のこと。

# 理論

17平均理論の導入として、SeventeenTonePianoProject :17音理論に目を通すとよい。もう1つの導入として、George SecorのThe 17-tone Puzzleにも目を通すとよい。17edo Solfege.17平均律テトラコード.Proyect 17-Perúも参照のこと。

17平均律は2.3.25.7.11.13サブグループテンペラメントとしてもっともらしく扱うことができる。それはとても計算されている。7リミット周波数比は一般的に、他の整数と同じぐらい良く現れないけども。

# コンマをなだらかにする

17平均律を< 17 27 39 48 59 63 |ヴァルとみなした時、次のリストのコンマをテンパーアウトする。

メモ：17-comma、avicennma、chromatic semitoneは比較的大きいサイズにもかかわらず、すべて13リミットの特徴的なヴァルによりテンパーアウトされる。
