A Guitar Lesson To Help You Test Your Note Knowledge.Written by Craig Bassett (The Guitar Solutions Expert)
In this guitar lesson we look at a great way to test your note knowledge of guitar fretboard. But before we look at that, why even bother learning notes? Knowing notes on your guitar fretboard is an essential skill. Here are a FEW of benefits that you'll gain if you have fantastic guitar fretboard knowledge… 1. You'll learn how to apply music theory to guitar much more quickly. In my opinion there's no point learning music theory if you can't PLAY it! 2. Your creativity will increase. You'll be able to think of new and unique ways of playing chords and scales. If you don't know notes on guitar fretboard, you'll be stuck playing same chord and scale fingerings that everyone uses. 3. You'll become a better musician. Great musicians don't just think in terms of chord shapes or scale fingerings. They think in terms of NOTES. 4. You'll save yourself hundreds (if not thousands!) of hours of frustration. By knowing notes on fretboard you'll be able to understand, learn and memorize things faster.
| | How to Tune Your Model Airplane EngineWritten by Andre McFayden
Tuning is simply adjusting your engine for peak performance. The factory-fresh settings may be a good starting point. However, you may need to compensate for higher altitudes, or for temperature changes with seasons. Changes in fuel type or engine wear, may also require a tune-up. Relatively more fuel to air is known as a "rich" mixture, while opposite is known as a "lean" mixture. A lean mixture generates more power, but also generates more heat. Too much heat could damage engine. A rich mixture generates less power and less heat. Too rich and engine might quit while you're flying. The popular twin-needle carburetor has two needle valves. The high speed needle controls total fuel flow into engine, and affects engine's behavior from half to full throttle. The low speed needle tends to have more of an effect from half throttle down to idle. Both low and high speed needles can be richened (counterclockwise turning), or leaned (clockwise turning). Tuning Procedure: 1) Start with factory recommended needle valve settings. 2) Start engine. 3) With engine or aircraft secured, open throttle to full. 4) Lean high speed needle slowly and watch and listen: Too rich: lots of smoke, low pitched sound Leaner: reduced smoke, sound starts changing to higher pitch Leaner still: little smoke, max rpm reached Too lean: very little smoke, max rpm can be heard falling off. Open needle valve up 20 or 30 degrees from this point. If you have a tachometer, open needle about 300 rpm less than max.
