You answered....FALSE

Did you catch the fact that the F#7 is not truly in the Key of D? You're pretty bright.

But wait a second. After just fifteen minutes of working with the Chord Wheel, a complete beginner would also recognize that the F#7 also functions as the 'III Chord.' So although it's not truly in the Key of D, it's commonly used in many popular tunes in the Key of D that it will sound great for variety. If you recognized this as well but still answered true, then YOU'RE RIGHT.

If you just picked this answer to discover the actual answer (or you guessed), we've got great news for you: This type of question will never bother you again and the benefits that you are certain this type of knowledge will bring you will soon be yours. Get yourself a Chord Wheel and start making better music today! If you don't and just keep slouching your way into the world of music thinking that you're an accomplished musician YOU'RE WRONG!

Practically every musician educated in music theory will admit that, like many disciplines, mastery of the concepts slip away quite rapidly without continuous use. So if you've studied these concepts extensively in your past yet still didn't answer these questions quite as fast as you'd like, then grab a Chord Wheel. After all, it's you're music!
