What is a 7th chord?!
Question: What is a 7th chord!?
Not sure which kind of 7th it is, in my jazz music it says "C7"!. It is the solo section in "Basically Blues", the first measure, and I have know idea what to do! there are other chords in there and I can learn them if i knew what they were, like "Bmi7" or "G6"!. This is a really cool piece, and I can't wait to see how it turns out!Www@Enter-QA@Com

Another poster said it well when he called C7 a dominant chord!. Since dominant chords and their scales occur naturally off the fifth scale tone of a major scale, C7 is the dominant of F, so the primary scale choice is a C scale which uses the notes from F major (including the Bb, which is the seventh of the root, C)!.
Philip U, I'll recommend using the chord syllabus to the foreword of the New Real Books; in it every conceivable chord is shown- including advanced notions like 9ths, 11th, 13ths, and even slash chords (sometimes used as an abbreviation for a 9sus chord)!. Almost all the examples use C as a root, so you would need to move patterns to the root shown in the chart!. If at all possible, use a piano or even small keyboard (yes, even a Casio or other home portable will do, but be sure to transpose appropriately for your instrument) to develop your sense of intervals in both a visual and listening sense!. For now, here are the spellings of the three examples you cited:
C7: C E G Bb
Bmi7 B D F# A (scale could be related to A, G, or D major - depends on other chords around it and/or the melody, if any)
G6 G B D E (could be related to G or D major- it's D major if any melody note is a C# instead of a C)!.

A seventh chord has the major 3rd and seventh notes, as well as possibly the root and fifth!. A minor seventh has the same but with a minor third (which is one half step down)!. A sixth has a major third and the sixth (instead of the seventh) and possibly the root!.Www@Enter-QA@Com
C7 is a dominant 7th!. That is 1, 3, 5, and flat 7!. If you use 1 3, 5, 7 it's a major seventh ( C Maj 7 )Www@Enter-QA@Com
