Sure. You can search within our forum for:
- "Straight right-wrist" vs "deviated/Segovia/abducted/bent/ wrist".
- Be sure to look-up "4th finger approach". This is a pretty big deal, in my opinion.
- Left-thumb position is hotly contested, but I'm a convert to the new "Behind or to the left of the first finger school".
- And my favorite, "2 hours of scales will teach you everything you need to know about technique".
- Most of the 20th century method books show a pronated left-hand when demonstrating where to put your finger for each note. A few of the new 21 century books have this corrected.
- The old books almost always show too much distance between the left hand and the neck.
-Open Hand school vs Flat Hand school
On another related note...
I try to keep to this sequence when I teach.
Mechanics combine into techniques (or segments), which combine into phrases. -Lawrence McDonald
Mechanics (defn) -a single motion in one part of the body. These need to be as physio-mechanically efficient and as effortless as possible. This is probably the most critical phase of instruction. Efficiency equals security and speed. Eg., a single rest stroke, or left-hand finger-fall velocity. If your core mechanism has too much inefficiency and dysfunctional tension, your learning curve will be extended, and frustrating.
Techniques/Segments (defn) -a combination/grouping of 5-9 mechanics. Mechanics don't always combine nicely. There will need to be compromises. For example, when playing more than one finger on the same fret, as is found in the common "D" chord, those of us with bigger hands must momentarily pronate (a counter-clockwise rotation the left wrist), an fortunate but necessary mechanic which causes the 3rd finger to straighten beyond it's most normal flexion, which can mess-up the internal "fret-mapping" in the brain (called proprioception). Not the best, but the compromise works.
Advanced Techniques (defn) -combinations of 5-9 previously learned automatic techniques (groups of techniques, which are groups of mechanics).
Phrase (defn) -Groups of techniques that end in a cadence. Since I teach back-chaining, I like to think that most of my efforts are at the phrase level, and that I let the music tell us (the student and I) what we need to work on. This allows us to discover our inefficiencies and practice them in a musically satisfying way.
I could go on and on, but this is enough for now. All the best,
