As a practice I am trying to name the chords in each bar in Bach’s Prelude in C major.

Can you correct me if I am wrong? enter image description here

    Several mistakes! But this isn't what the site is about. The question will most likely be closed. – Tim Dec 29 '18 at 15:55
  • This is not just a particular song: this is the ultimate piano piece for beginners learning reading sheet music, grand staff, chords, harmony, chord progressions. The question isn't off topic and not more basical than many others that are not closed ... He could have asked what are the chords of prelude 1 of wtc and you wouldn't have intervented. – Albrecht Hügli Jan 8 at 19:33
  • @AlbrechtHügli - Nah, I would have intervened: this still isn't a place where you ask for what are basically lead sheets. I don't care how famous the piece is: figure out the chords of the 1st movement of Beethoven's Fifth yourself. – Dekkadeci Jan 10 at 16:46
  • ok, I agree with that there are too many elementary questions here that ought to be just ignored or closed from the beginning, I have to study better the rules for asking ... – Albrecht Hügli Jan 10 at 16:51

Try writing down all the note names in one bar and try to arrange them so that they form a chord. E.g. in the second bar you have:

CDADF

By trial and error you can put this in the form:

DFAC

where the jump between each note is a third. This spells a Dm7 chord. Finally, note that the C is in the bass so you should probably write this as Dm7/C.

Also, if there are no accidentals (♯ or ♭) then the chord must be diatonic to the key you are in. In C major there is no A (major) chord, but only an Am. Hence you are wrong in the fifth bar. However, as been pointed out, you have several errors, so it is best to go through everything.

yes, there are several faults. you can find them yourself: Dm = Dm/C as the IIm7 (inversion) Am = Am/C (inversion) D7/C as a (V2) or V-V7 in 1st inversion I suppose you know yourself the inversion of the other chords

further you have a C# dim7/G leading to Dm and a B dim7/F leading to C, both as VII° 2nd inversion to the following chord in 1st inversion. I can poste you here the link or the copy the analysis of the whole preludium. I know there is one of HERMANN KELLER and SIEGLIND BRUHyou'll find also more than one analysis in youtube. anyway:it's a good practice to try this and to note just chords instead of the all the music and each motif. hope you got it: chords of prelude in C J.S. Bach wtc

C Dm/C G7/B C

Am/C D7/C G/B C

Am D7 G

C#dim7/G Dm/F Bdim C/E

Dm G7 C

try to finish your task by studying lessons 40-44 in of this site, that I've just found right here as advertisement on the right of your question.

    I disagree with this hold - questions like this can VERY WELL be useful for future users. I move to remove the hold. That being said, you started well, however, look again at the chords you've marked as "D" and pay attention to the key, a lot of the D chords are actually not major, yet you've used the same marking for them and the two that actually ARE major chords, you may want to mark the D major chords with a triangle or mark the minor chords with a minus to distinguish them. (For example, measure 2 is a minor, measure 6 is a major!) :) – KoshVorlon Dec 31 '18 at 13:12
