Questions re. music notation

[wirralaccordion]

I am looking at music written for accordion which is just the melody line. The bass chords are written over the notes but only once until they change. Sometimes I am seeing two letters seperated by a slash such as G/B. Does this mean that the G chord is played with the single note B simultaneously? i.e. bass + counterbass together?
One two letter variation is E9/B written above F sharp in the key of B flat - What is this?
Finally I see F7 which is OK but followed by F(triangle)7 - again what is this?

Many thanks.

There is no true standard notation for the bass. But I would interpret G/B as playing G major in whichever rhythm is appropriate but instead of starting (each measure) with the G you start with B. SO not bass+counterbas but chord with the second letter as the alternative base note.

Then E9/B would mean you play the chord of E9 (E G# B D F#, which is done by playing E major + B minor) and using B as the alternative base note (instead of E).

The notation with the triangle I do not know.

The "triangle 7" is jazz shorthand for a major seventh chord. (Actually, in jazz it can be further construed as a placeholder for "something major that sounds good here", and you can frequently substitute maj6, maj9, etc.)

There is no button for maj7, of course, but there are many ways to deal with it anyway:

• Play a regular major chord and just ignore the maj7 part.
• Play a regular major chord in the LH and add the maj7 chord tone as a RH harmony to the melody (assuming it's not already the melody note, that is). For an Fmaj7, the maj7 note is E.
• Keep the bass note, but play a minor chord based on the 3rd of the original chord, either instead of or with the major chord. So for Fmaj7, you could play F bass + A minor, or F bass +F major + A minor (ouch!)
• Same as above, but instead using the major chord "one floor up" (i.e., based on the 5th of the original chord). This technically makes it an Fmaj9, but you can often get away with it and it's easier to play! For Fmaj7, you could therefore play F bass + G major, or F bass + F major + G major

And yes, Paul is correct about the "slash chord" notation. In the sort of notation you seem to be looking at (called a "lead sheet" by the way), it means to use a bass note other than the typical root of the chord, in whatever pattern is appropriate for the music. G/B would be pronounced "Gee over Bee" and basically represents a G chord in first inversion.

What's the song you're working on?

Jeff,
FYI The songs are
G/B - I love you and don't you forget it
E9/B - Ain't she sweet
Cheers
