今回は、DAMというカラオケシリーズにおける2016~2023年の年間カラオケトップソング（1位~50位）のデータを利用しようと思う。また、それぞれの曲の特徴を明らかにするため、音楽サブスクリプション「Spotify」のAPIから曲のテンポやキーの高さなどの情報を取得している。

それぞれのデータの取得方法
・DAMカラオケラトップソング50・・・DAMの公式サイトのカラオケランキング(https://www.clubdam.com/ranking/2023/) に載っている2016年から2023年の楽曲別ランキングTOP50のデータから取得
・SpotifyAPI・・・音楽サブスクリプションSpotifyが提供している「Spotify for Developers」(https://developer.spotify.com/) から自身のSpotifyアカウントの楽曲情報等をGoogle Colaboratory(ブラウザでPythonができるサービス)を介して取得している。

2016~2023年のデータを集計したものが以下である。
・トップ50位にランキング入りした年
・曲のジャンル
・曲名
・アーティスト名
・ランキング順位
・主キー
・テンポ
を左から順に記している。なお、サブスクリプションが解禁されていない楽曲などで情報が取得不可なデータ要素は空白になっており、今回の分析対象から外すものとする。

最近のカラオケ曲が難しいと思う件について

by okonogi

◆テーマ

音楽界では、2020年代あたりからYOASOBIやAdoをはじめとした日本の音楽に新たな印象を残すアーティストが台頭し、歴史においても令和時代を象徴するような音楽の特色が見られる。\n私はよくカラオケに行くのだが、どうも最近のカラオケトップソングは6〜7年前のそれより明らかに難しくなったと感じることが多い。先に述べた新しい音楽のブームが影響していることに間違いはないと思うが、具体的に何がどのように変化したのだろうかと気になった。今回はその疑問の答えを可視化してみる。
\n

\n「近年におけるカラオケトップソングの特徴を、過去と比較し可視化する」

\nをテーマにし、調べて判明した事実を述べようと思う。

◆分析：ジャンル

最初はジャンルの変化について分析をした。上のテーブル表を見る限り、明らかにJ-POPが多いことがわかるので「J-POP」か「J-POP以外」の二択で集計し、以下がそのグラフである。J-POP・ロックなど二つ以上のジャンルを有する曲はJ-POP以外として扱っている。

2016年ではJ-POPの楽曲数は32曲であるが、年が経つにつれてその曲数は上昇し、2022・2023年では45曲以上となっている。これを割合換算すると、2016年で約64%だったに対して2022年以降は約90%と大きな差が生じており、明らかに誤差ではないことわかる。これにより、

◆分析：主キー・テンポ

続いて主キーとテンポの変化についてグラフ化してみる。各年の平均主キーとテンポを取得し、それを折れ線グラフ上にすることで可視化を図る。なお、SpotifyAPIにおける主キーは音階を0〜11段階の数字で割り振っており、
ド=0・ド＃=1・レ=2・レ＃=3・ミ=4・ファ=5・ファ＃=6・ソ=7・ソ＃=8・ラ=9・ラ＃=10・シ=11
のように表される。

平均主キーと平均テンポについて可視化した結果、どちらも特徴的な傾向が見られない。平均主キーは大体5.0~6.0(ファ~ファ＃)の間を取っており、大きな変化があるとは言えず、平均テンポに関しても、120台を平たく移り変わっている。これにより、

◆ここまでを見て

これまでに、ジャンル・主キー・テンポについて調べたが、J-POPが増えているという傾向しか見られていない。私は、最近の曲が難しいと感じる理由にテンポや音程が関わっていると思っていたのでこの結果には意外だと感じる。
では、私が難しくなったと感じるのはどこから来ているのか、はたまた難しくなってないのか。
そこで、さらに詳しく調査するためにSpotifyAPIから曲の潜在的な部分に見られるようなデータを取得し、それらを下のテーブルにまとめた。

\n 追加した項目一覧
・speechiness・・・ラップや話し言葉のようなスピーチ感があるかどうかを0~1で可視化
・valence・・・悲観・楽観度(悲観的なら0に近く、楽観的なら1に近い)
・energy・・・エネルギッシュさ(0~1の値でよりエネルギッシュなほど1に近い)
・loudness・・・音圧(単位：-dB　正の値に近い方が音圧は大きい)

では、新たに追加したspeechiness、valence、energy、loudnessについて、先ほどと同じように年ごとに平均値を出して可視化してみようと思う。

◆分析:speechiness・valence・energy・loudness

","pinned":false,"hidden":false,"mode":"md","author":"$undefined","summary":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"","database":"$undefined"},{"id":2418,"value":"viewof selectanay = Inputs.select(\n [\"speechiness\", \"valence\", \"energy\", \"loudness\"]\n)","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":2430,"value":"$33","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":2500,"value":"

それぞれの項目のグラフを確認し、大まかな特徴を述べると
・speechiness・・・2020年まで比較的低い値だが2021年以降高水準の値
・valence・・・2018年が異常に高いがそれを除けば上昇傾向
・energy・・・2020年まで上昇と下降を繰り返すが2020年以降上昇傾向
・loudness・・・2018年にかけて上昇傾向、それ以降は高水準を保っている
ということが見てとれるだろう。つまり、全ての項目において
上昇傾向・または近年にかけて高水準
になっていることがわかる。

◆これまでの分析のまとめ

これまでに分析したデータにおいて、近年にかけての変化が見られたものをまとめると、

\n ・カラオケトップソングにおいて、近年ではよりJ-POPが歌われている
・2021年以降においてよりスピーチ感のある曲がランキングに多く、年々上昇
・2019年以降においてより楽観的な曲がランキングに多い
・2020年以降においてよりエネルギッシュな曲がランキングに多く年々上昇
・2018年以降においてより音量が大きい曲がランキングに多い

\n \n

\n という結果になった。
確かに、ラップ口調のようなスピーチ感のあふれる曲は早口になって難しそうであり、楽観的やエネルギッシュな曲は、ゆっくりな曲調よりパワフルで激しい印象がある。音量・音圧が必要とされる曲も肺や喉の消耗が大きく難しいはずである。
今回の後半ではSpotifyAPIを用いて、普段滅多に数値化できない様な要素を可視化し、特徴を追求した。\n 近年のカラオケトップソングでは、そのような表面には現れにくい曲の潜在的な要素があることがわかった。近年のカラオケソングが難しいと感じたのは、それらを感覚で受け取っていたからなのかもしれない。

しかし、疑問点も残る。「カラオケトップソングにおいて、近年ではよりJ-POPが歌われている」のは何故だろうか。普通に考えれば、J-POP\nは日本で最もポピュラーで、パンクや演歌・K-POPなどと比べたら確実に歌いやすいだろう。実際に下図において、J-POPとそれ以外の今回調べた要素について簡単なマップを制作したが、J-POP以外の方が数値的にも難しく感じる。それも関わらず、近年上昇しているとなると近年の曲が難しく感じることと矛盾する。

2016年から既に上昇傾向であることから、この背景には、演歌の人口の過疎化などを含んだ現代の音楽風潮が原因にあるのかも知れないが、今回の可視化でははっきりとさせることができなかった。また機会があれば今後の展望として分析対象に含めたいと思う。
