Even vocalists??? LOL I get the drift.  Like lipping up on a sax or something to match what's going on???  How do they match the piano or other fixed keyboard instruments or are all the keyboards, just "out of tune" with the rest of the orchestra on certain passages? <table width=100%> <tr valign=top> <td>From: <td>"Tom Rhea, Jr." <rheapiano@cox.net> <tr valign=top> <td>To: <td><pianotech@ptg.org> <tr valign=top> <td>Date: <td>09/27/2011 03:07 PM <tr valign=top> <td>Subject: <td>Re: [pianotech] theory question</table> <hr noshade> Hi Paul,   An instrumentalist generally only plays one note at a time but all of the notes of the score must be harmonically related.  That’s true even with a vocalist.  If you look at a score (piano, orchestral, choral, etc) and analyze each chord, you’ll find that they can be broken down into a very logical, though sometimes extremely complex, structure.  What confuses me at times, is a note (G# for instance) that crosses a bar line and becomes an A flat.  Musically, they’re the same note but harmonically they’re not because the other notes in the chord have changed, making the entire structure into something different, even though the two notes (G# and A flat) sound the same to the ear.  Instrumentalists, but especially vocalists, have to be aware that the A flat must be tuned slightly when going from a G# because of the inharmonicity within the chord structure.  As piano technicians, we have to be aware of the same inharmonicity when tuning since some of the intervals need to be stretched or compressed slightly to match the temperament.  The same occurs in instrumental or vocal music, too, especially with string instrumentalists and vocalists.   I hope this hasn’t been too long-winded and makes some sort of sense.   Regards, Tom     <div align=center> <hr></div> From: pianotech-bounces@ptg.org [<a href="mailto:pianotech-bounces@ptg.org">mailto:pianotech-bounces@ptg.org</a>] On Behalf Of Paul T Williams Sent: Tuesday, September 27, 2011 3:30 PM To: pianotech@ptg.org Subject: Re: [pianotech] theory question   Ahhh!   Makes sense to me. Thanks for clarifying this.  I always wondered that, too.  But;  why do this, when the notes are just written in the score?  Would a bassist wonder why he/she is playing an E or G when it's a C chord?  I've always just played what's written.

Best, Paul <table width=100%> <tr valign=top> <td width=14%>From: <td width=85%>"Tom Rhea, Jr." <rheapiano@cox.net> <tr valign=top> <td>To: <td><joegarrett@earthlink.net>, <pianotech@ptg.org> <tr valign=top> <td>Date: <td>09/27/2011 02:04 PM <tr valign=top> <td>Subject: <td>Re: [pianotech] theory question</table>   <div align=center> <hr noshade></div> Hi Joe, et al, The actual theory behind this convention is this: Consider the CEG major chord and the note positions when being played.  All the notes are said to be in their root positions. When a first inversion of the CEG chord is being played, the E and G are in their root positions but the C has been moved up an octave and is now a 4th interval above the highest adjacent root note, the G.  This position, EGC, is said to be a C Major 4 or first inversion of the C Major chord. In the second inversion of the CEG chord, the only note still in its root position is the G.  The C and E are moved an octave above their root positions, such that the E is a 6th interval above the G (in its root position) and the C is a 4th interval from the G (in its root position), hence a C Major 6/4. All of the chords are spelled from the bottom.  However, the intervals which comprise the inversions are labeled from the highest note still in its root position to the one or two notes that have been moved up an octave from their root positions, either a 4th interval for a first inversion or a 6th and a 4th interval for a second inversion.  The labeling of the inversion intervals is always from the highest interval first. I hope this helps with understanding the theory question.

You count from the bottom up. A "6" is the interval between the E and the C when in first inversion. In second inversion, G, C, E, there is a 4th between the G-C and an "6" between the G-E." Ken Gerler (I was a theory major in college) Hmmm? if that were the case, then the later would be a 4/6 rather than a 6/4. Right?<G> Personally, I prefer the Jazz Musicians way of saying something like "the C chord with a G in the bass.<G> That's my take on that. Joe Joe Garrett, R.P.T.
