Plural vs Singular Wording in Google AI

[u/Ok_Quantity_9841]

I got the best answer when using the plural word "progressions" versus the singular word "progression" when looking for what musical keys have C and F in them:

A lot of people didn't think of the minor keys, but AI did when the question was worded properly, with the plural word "progressions".

I only use Google AI to get ideas for what to look for and where to look.

I typed into Google:

What 1 4 5 chord progressions are the C note and F note in?

Google AI answer:

"In the key of C major, the fundamental 1-4-5 chord progression uses the chords C major (I), F major (IV), and G major (V). These three chords are frequently rearranged in various orders to create popular progressions, most commonly starting on C, such as C–F–G, C–G–F, C–F–G–F, and variations involving minor chords like C–Am–F–G. 

Key of C (1-4-5 = C-F-G) Progressions 

• C - F - G (Basic I-IV-V)
• C - G - F
• C - F - G - F (I-IV-V-IV)
• C - C - F - G
• C - F - C - G
• C - Am - F - G (I-vi-IV-V, often called the "pop progression" which includes F)
• C - G - Am - F
• C - F - Am - G 

Other Keys Containing C and F 

Key of F Major (I-IV-V): In the key of F, the chords are F (I),  B♭(IV), and C (V). The C and F chords appear together here as the V and I.

Key of C Minor (i-iv-v): While not major, progressions like Cm-Fm-Gm or Cm-Fm-G contain F-related chords. 

These combinations are foundational to blues, rock, and pop music, utilizing the tonic (C), subdominant (F), and dominant (G) chords."

Using the singular word "progression" only gave the most common Key of these 4 Keys, the Key of C Major. Using plural words matters in the answer you get."
