Welcome to Music: Practice & Theory Stack Exchange

Music Stack Exchange is a question and answer site for musicians, students, and enthusiasts. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about music practice, performance, composition, technique, theory, or history.

We're a little bit different from other sites. Here's how:


Ask questions, get answers, no distractions

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

...and answers.

up vote

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

accept

The person who asked can mark one answer as "accepted".

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

What is the chord containing C, D, F#?

up vote 14 down vote favorite

Its inversion "D F# C" appeared in the 10th measure of the Prelude in C Major(BWV 846).

Seems like a usual triad, but I just can't fit it into pattern of any triad.

Its most possible basic form of triad I could guess is "C D F#", which is diminished third + minor fifth.

Does it has a name?

It's V/V. There's a slight modulation from C, and it goes to G, the V of C. Hardly a mod., the piece needs to get back home to C. To get there, it uses the V of G, which is D7 - hence the notes D, F# and C. It's part of the cycle of fourths/fifths - Am>D7>G7>C.

That could be the dominant seventh chord of G Major with the 5th omitted, so D F# A C but with the fifth left out, you can do that. So basically G:V7-5.


Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

Ask about...

  • practice & performance technique
  • music theory and notation, history, or composition
  • technical analysis of a specific, complete work, or well defined section thereof
  • instrument maintenance
  • usage of specific music software

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

Don't ask about...

  • Anything not directly related to music practice, performance, composition, technique, theory, or history
  • Questions that are primarily opinion-based or recommendations
  • Identifying a song, style/genre, instrument/equipment, technique, chord progression, etc.
  • Questions with too many possible answers or that would require an extremely long answer

Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

It could be called D7 (no5), but it's fairly common to leave out the 5 from any chord (except 'power chords'!!) because there are elements of that pitch sounding in the harmonics of the root. So, no need to change the name. That apart, Bach probably didn't think in terms of chords like we tend to now, I think. - Tim Nov 18 at 9:44
