平均“命中率”是什么樣的 (What an Average ‘Hit’ looks like)

Before we break the song down, let us have a brief analysis of what the greatest hits of all time had in common. I have picked 1500 songs ( charting hits ) right from the ’50s to the’10s, spread across all the popular genres ( Find the Spotify playlist here ).To keep things simple, let’s focus only on one key attribute: The Tempo

在分解歌曲之前，讓我們簡要分析一下有史以來最偉大的歌曲的共同點。 從50年代到10年代，我已經挑選了1500首歌曲(排行榜中的熱門歌曲)，分布在所有流行類型中(在此處找到Spotify播放列表)。為簡單起見，我們只關注一個關鍵屬性： The Tempo

Histogram (Tempo)直方圖 (速度)

We can infer that most tracks fall in the 100–130 BMP range. However, it is still fairly spread out to draw any homogeneity. let’s see how the tempo varies while playing these tracks.

我們可以推斷出大多數軌道都在100-130 BMP范圍內。 但是，它仍然相當分散以得出任何同質性。 讓我們看看在播放這些曲目時節奏如何變化。

播放速度變化 (Tempo Changes in the Playback)

For simplicity, we can also consider the x-axis as time為簡單起見，我們也可以將x軸視為時間

Every track is broken down into sections. Each line represents a track and how its tempo changes over its sections. We can see that almost all the tracks make a fairly straight line — i.e, the tempo remains constant throughout the track.

每個軌道都分為幾部分。 每條線代表一個音軌以及其節拍如何在其各個部分中變化。 我們可以看到幾乎所有的音軌都形成一條直線-即， 速度在整個音軌中保持恒定。

Histogram ( Tempo Standard Deviations for each track )直方圖 (每個音軌的速度標準偏差)

Only 5 Tracks ( 0.4 % / plot in red ) were observed to have a standard deviation of more than 30 BPM — i.e They have significant tempo variation. These tracks are:

僅觀察到5條音軌(紅色為0.4％/圖)的標準偏差超過30 BPM-即它們具有明顯的速度變化。 這些軌道是：

Forever Now, Green Day

永遠現在， 綠色的日子

I Can’t Stop Loving You, Ray Charles

我不能停止愛你， 雷·查爾斯

I Hate U, I Love U, Gnash

我討厭你，我愛你， 納什

Isn’t She Lovely, Stevie Wonder

她不是很可愛嗎， 史蒂夫·旺德 ( Stevie Wonder)

Bohemian Rhapsody, Queen ( Surprise Surprise )

女王波希米亞狂想曲 (Surprise Surprise)

分解這些足跡 (Breaking these tracks down)

Let’s briefly look at the structure of the first 4 tracks using:

讓我們使用以下內容簡要查看前4條軌道的結構：

Waveplot — Plots the amplitude over time.

波形圖—繪制隨時間變化的幅度。

Spectrogram — Displays signal strength over time at the various frequencies present in a track.

頻譜圖 —顯示軌道中各種頻率下隨時間變化的信號強度。

We can observe a fair amount of repetition in the pattern. This accounts for the generic verse/chorus format most songs follow. Before we address that, let’s take a look at the spectrograms.

我們可以在模式中觀察到相當多的重復 。 這說明了大多數歌曲都遵循的通用詩歌/合唱格式。 在解決這個問題之前，讓我們看一下頻譜圖。

Spectrograms are good indicators of the genre of a song頻譜圖是歌曲類型的良好指示

We can draw a very similar observation here. Apart from the repeating patterns, the spread of frequencies remains almost consistent throughout the timescale, which also means that each track can be conclusively classified into one genre.

我們可以在這里得出非常相似的觀察結果。 除重復模式外，頻率分布在整個時間范圍內幾乎保持一致，這也意味著可以將每個軌道最終歸為一類。

Almost all songs that reach the top of the charts use some variety of the verse/chorus format. A verse part leads into a repeating, climactic chorus with some kind of a build and release (the loud/quiet/loud idea). Take a few seconds and think of a song — — — — That one section that you started humming, the same part you sing to your friends when they ask “how does that song go again?” is called the Hook (Because it quite literally ‘hooks’ into your memory). All these elements carefully put together are a safe bet for a track to be a hit.

幾乎所有排在排行榜頂部的歌曲都使用各種曲調/合唱格式。 一個詩句部分導致重復的，高潮的合唱，具有某種構建和釋放(大聲/安靜/大聲的想法)。 花費幾秒鐘的時間，想一首歌— — — —您開始哼唱的那一段，當您的朋友問“那首歌又如何？”時，您唱給朋友的那部分 被稱為“ 掛鉤” (因為它確實“鉤”入了您的記憶)。 所有這些元素都經過精心組合，是確保曲目成功的可靠選擇。

波西米亞狂想曲有何不同？ (How is Bohemian Rhapsody Different?)

The Waveplot shows little to no signs of pattern repetition, the Spectrogram also displays a divergent spread of frequency distribution — which doesn’t follow the ‘generic hit formula’ of a verse/chorus format. This goes to uncover a rather unfamiliar structure that Bohemian Rhapsody carries, and that is exactly what makes it a masterpiece, the fact that it not a song but indeed a rhapsody.

Waveplot幾乎沒有顯示出圖案重復的跡象，頻譜圖還顯示了頻率分布的發散分布-不遵循詩歌/合唱格式的“通用命中公式”。 這就發現了波西米亞狂想曲所帶有的一種相當陌生的結構， 這正是使它成為杰作的原因 ， 它不是一首歌，而是一首狂想曲。

A Rhapsody is a piece of music that is meant to express different kinds of emotions and does not have a regular form. It is often classical and through-composed. Which means it has got no repeating sections.

狂想曲是一種音樂，旨在表達不同的情感，并且沒有規則的形式。 它通常是經典的并且是貫穿整個過程的。 這意味著它沒有重復的部分。

We can break it down into 5 distinct sections, each can be classified into a genre and posses its corresponding audio features.

我們可以將其分為5個不同的部分，每個部分都可以分類為一個流派，并具有其相應的音頻功能。

Queen takes musical genres and analogies the audience is already familiar with and adapts them to the narrative of their songs. They also do the same with the structure, by taking the well-known format of the Hero’s Journey and adapt it into a song unlike anything else in the history of rock music. This combination is what makes the song instantly approachable, yet still exciting even after all these years. This is how a song as weird and disjointed as Bohemian Rhapsody became a huge charting hit and also proves to be emotionally resonant for decades to come.

皇后樂隊采用音樂風格和類比，使聽眾已經很熟悉，并使其適應他們的歌曲敘事。 他們還采用了《 英雄之旅》的著名格式，并將其改編成與搖滾音樂歷史上任何其他歌曲都不相同的歌曲，從而對結構進行了同樣的修改。 這種結合使這首歌立即平易近人，即使經過了這些年，仍然令人興奮。 這就是波西米亞狂想曲中那首怪異而脫節的歌曲如何成為熱門唱片排行榜，并且在接下來的幾十年中也被證明在情感上引起共鳴。
