Rounds 4 and 5 Wrap Up: "On the 1's" and "On the 2's"

My strategy for analyzing no.1 hits on the Billboard Hot 100 has been to take glimpses of the songs, one decade at a time.  Using the first week of August as my target date, I started the whole thing off in August of 1958 with the inaugural no.1 hit "Poor Little Fool" by Ricky Nelson.  From there, I visited 1968, 78, so and so forth.  

The last 12 analyses have covered 1961 - 2012.  After analyzing chords, melody and lyrics, I compiled a list of common musical threads that were present in each.  Though I have done for each analyses, I started a fresh list and built on it with each song.  The "final" list ended up with 7 reoccurring musical elements:

Repetitive Melodic Motifs - the overall melody repeats itself both with identical phrases and with similar intervalic or rhythmic motion

Stepwise Motion Common in Melody - 2nds, major or minor, are the primary melodic interval

Hook Uses Song Title - The hook, or catchiest part of the song, utilizes the title

Vocal Harmony - Prevalent vocal arranging through parallel harmony, countermelody and/or call and response

Texture Changes - Timbre and/or dynamic change through instrumental arrangement

Strong Harmonic Motion from V-I - Chord progression that sees V7 resolving to I (or i)

New Material at the End - the closing section of the song features a new melody and/or chord progression

Below, I have summarized each song in relation to these commonalities.  Please take a look at individual entries for each songs analyzed, by the decades: "On the 1's" (1961 - 2011) and "On the 2's" (2012 - 1962). 

Common Threads - 1961 - 2012

A few things stick out.....

Every song contains repeated melodic motifs.  Repetition took a couple of different forms from the use of similar intervals and rhythms to straight out repeats of phrases.  Either way, this is the common thread that makes the most sense, as listeners generally gravitate to predictability.  

Every song on this list includes the title of the song in the hook.  It's interesting that this trend, certainly seen in many modern songs, has been happening since the early 60's.  I know there are exceptions to the rule, but they are few and far between....(notable exception: Drake's 2018 no.1 "In My Feelings")

Prominent stepwise motion was present in almost every song.  While there were 2nds in the melody, Bobby Lewis's 1961 contribution, "Tossin' and Turnin'," leaped around quite a bit.  It makes sense that stepwise melodies are favored by many listeners.  It's also worth mentioning that most of the time, melodies are diatonic.  I may keep closer tabs on this moving forward.  

Texture changes were present on almost every song as well.  The two songs that had static texture from beginning to end were Madonna's "This Used To Be My Playground" (1992) and Nelly's "Hot In Herre" (2012).  Both of those stayed in the same sonic space, dominated by keyboard sounds with no relent.  The other compositions have some change in texture from less drums, to more drums, to no drums.  The same goes for other instruments, like guitars, bass, horns, etc.  There are further exponential variables when you consider way instruments can be grouped to get different timbres and sonic textures.

Many songs use vocal harmony, which coincidentally can be used to change the texture.  The only song above that did have vocal harmony without texture change was Madonna.  This is mostly due to the harmony being present a majority of the time, so nothing ever really feels different.  She provides the harmony herself, keeping the timbre even more unified.

After analyzing this data, I see the "new material at the end" element was really just a reaction to three songs in a row (2011, 2001, 1991).  As you can see, it doesn't occur again outside of 1992, which barely qualified with a 4 measure variation on previous themes.  

A curious element is harmonic motion from V-I.  7 out of 8 songs between 1961 and 1992 contained V-I motion.  The only one that didn't was "Eye of The Tiger," mostly due to the popular minor key progression of i - bVI - bVII....no V's are really needed.  Songs between 2001 and 2012 come up empty though, indicating an abandonment of this traditional cadence.  In keeping with that theme:

Look at those chord counts!  With the exception of "Eye Of The Tiger," the curve is generally higher before the 2000's.  After that, no.1 hits seem to utilize less chords.  This can also be seen in the lack of V-I resolutions.    Check out the line graph below to see how the number of chords used in these no.1 hits has changed through the years.

Let's take a look at some compiled data regarding singer gender, key signatures, tempo, song length, chord progressions and sections. 

Combining the above data with the previous data taken from the round 3 wrap up, in 37 analyses, we see the following trends:

• 14/37 (38%) in a minor key (+2%)
• 12/37 (32%) have a tonal center of Ab (G#) or C
• 16/37 (43%) utilize one primary chord progression for the entire tune (-5%)
• 26/37 (70%) contain more than 2 sections (+2%)
• 7/37 (19%) have verse and chorus only (-5%) 
• 23/37 (62%) contain at least one bridge section (+10%)
• 14/37 (38%) utilize the bVII chord (-2%)
• 25/37 (68%) utilize the IV(iv) and I(i) chords (-4%)
• 34/37 (92%) are in duple (2/2 or 4/4) meter (+/- 0%)
• 23/37 (62%) feature a male lead singer (+6%)
• 35/37 (95%) use the title of the song in the hook (+3%)

• Average length - 4:03.  

Looking at these points, I am thinking of a few things:

• Major keys are slightly more favored than minor keys.
• Tonal centers are all over the map with 12/37 songs using C or Ab as the home pitch!?
• Songs generally have more than 2 sections, which usually includes a bridge.....if there is a bridge, that usually indicates a verse and chorus as well.  
• Duple meter is king.
• I and IV (i and iv) chords are common in chord progressions
• Slightly more male than female lead singers
• Using the title in the hook is almost universal

So that's a wrap on these two rounds of analyses.  Once again, I am finding myself discovering some cool new songs and appreciating ones I may not have given a chance.  

In the past few weeks, I have been listening to lots of pop radio, mostly to occupy my children (ages 10 and 8) on car rides.  They are very familiar with many top 40 songs and actively sing along.   When I have had enough of a particular song, I zone out.  As the music fades to background music, it's not offensive and doesn't demand my attention, it's just pleasantly there.  Those are the two extremes that contribute to mass appeal.  I can be actively engaged in listening or just find comfort in the familiar well-mixed drone.

Up next time, I'm going to take stop in 2020 and analyze "Circles" by Post Malone. I recently learned it for a gig and figured I should write it up for posterity.  After that, we'll head resume with "On the 3's," heading to 2013.  Get ready for a continued dive into no.1 hits, through the decades.
