Godden Music can provides fully set up Sympathetic Harp Guitars, or we can add a Sympathetic Harp to your own guitar without any structural alteration. (It is fully removable.)

A sympathetic harp is an attachment  in the form of a harp that can be fitted to any acoustic guitar giving the instrument sympathetic string response. When fitted and strung the guitar becomes a sympathetic guitar (sound sample) The sound of the sympathetic response given  by the harp is similar to the sound of a sitar. The guitar can  than be  easily turned into any one of the following instruments by simply retuning, changing string configuration, or changing string action height

The Sympathetic Harp is constructed from select musically resonant hard woods, carbon graphite reinforced polymers. and they come with a studio quality pickup, stainless steel fittings, and tuners of your choice. 
The Harp is relatively easy to install, requires no structural alteration of the host guitar and is easily removed, leaving the instrument in it's original  unaltered condition. Once installed The Sympathetic Harp is easily be adapted to one these basic instruments types: the standard fretted style, the modal fretted style, the standard slide style. and the modal fretted slide style.

The Sympathetic Harp utilizes the principle of sympathetic resonance to activate the sympathetic strings. When the player plays a note on the main playing strings of the host guitar, the resonating string vibrate the face of the guitar which transfers energy to the sympathetic strings. Our Jawari bridge reacts to the slightest energy in the sympathetic strings. This vibration is fed back acoustically into the face of the guitar, as the same time the jawari bridge converts this energy into an electrical signal which can be amplified.

 

 

 

 

How much does it cost?

Option One: you send us a guitar and we install a harp to it.
We install a sympathetic Harp to your regularly fretted guitar. The harp cost on your guitar: $1150. The installation is done by Amber Godden, and Kalyan Godden. You ship us your guitar, we fit the sympathetic harp to it and send it back to you (Installation takes 2 weeks). We can  also pick up a guitar of your choosing from local or internet retailers and fit a Sympathetic Harp to it. To have (rhythm strings) Chicaris, Chicari posts, an extra jawari bridge, or  custom made raised nut and saddle, will cost extra.

We would strongly advise against having anyone other than Amber and Kalyan Godden doing the installation, as the harp must be fitted and the Jawari bridge tweaked by a Jawari expert. If the installation is not done correctly, the harp will not work properly.

Configurations

A fretted Sympathetic Harp Guitar
 Is a regular fretted guitar on which a sympathetic harp has been installed and the fourteen sympathetic strings are tuned to the equal temperament 12 note octave(ET).  ET is ideal for both chords and melody and any kind of music utilizing equal temperament such as: jazz, rock, pop, classical, bluegrass, to name a few.  With a few minor set-up adjustments the fretted Sympathetic Harp Guitar can  become a sitar guitar/raga  instrument played with a slide - Vina  style.

Modal configuration
Modal guitar sometimes called a Sitar guitar or raga guitar. A regular fretted guitar on which a sympathetic harp has been installed and strung and strung strings tuned in 12 tone equal temperament. This is a normally fretted guitar with the sympathetic strings tuned to the Equal Temperament.  Several of these sympathetics can be  set up to become Chickari or rhythm strings. the result is a guitar that sounds a lot like a sitar or Vina . This set up can be used with tonic modulations and chord sequences as well as fixed tonic modal music , Indian music, and western music experimental music

Hindustani slide configuration or Vina

Vina guitar is a regular steel string acoustic guitar on which a sympathetic harp has been installed, and the strings tuned using the raga scales of Indian music called - the Thats.  The main playing strings are raised with  a higher nut to allow the instrument to be played with a slide. The main playing strings are open tuned and the sympathetic strings are tuned to non tempered intervals ( sometimes referred to as the un tempered scale) or raga intervals. This results in a guitar that sounds a lot like a sitar ,sarod, or Vina, which is ideal for Indian music performance, or any model music form which uses non tempered intervals. The Vina style are often fitted ith Chiakri strings. these are an additional set of three rhythm strings. Unlike sympathetic strings, Chicari strings are struck with a plectrum or by the fingers as and they are usually tuned to the tonal center, the fifth, or the third of the rag being played.

Features

- relatively easily installed, requires no structural alteration of the guitar.

- easily removed, leaving the instrument in its original un altered condition.

- many instruments in one, easily reconfigured to become one of many different instruments.

The Sympathetic Harp comes with a studio quality pickup  pickup and stainless steel fittings.

 

 

 

 

A basic introduction to the octave.

The musical octave can be divided in to an infinite number of fractional intervals.  However there are only 66 usable musical notes. From these come the 22 main notes called the Just Intonation Scale. Also from these 66 intervals come the 22 Pure Tuning notes (Shrutis) used in classical Indian  music. The divisions that make up the 22 tones of just intonation are simple mathematical fractions:  2/1 = the octave, 3/2 = the fifth, 4/3 = the fourth, 5/4 = the third etc. From these come the fraction sets producing the just Intonation 12 note chromatic octave. From these notes come the seven Greek 8 note modes and the 5 note pentatonic scales.

Below are the 12 note fractions which make up harmonic partials that are common to the Chromatic Just Intonation Scale of C as well as the 12 note Pure Tuning Octave.

 

C -256HZ

C# - 273.306HZ

16/15
D - 288HZ 9/8
D# - 307.2HZ 6/5
E - 320HZ  5/4
F - 341.333HZ    4/3

G - 384HZ  3/2

A - 426.666HZ  5/3
A# - 460.8HZ 9/5
B - 480HZ  15/8
C - 512HZ 2/1

 

All the 22 main tones of the Just intonation Scale are the simplest fractions or harmonic relations to the tonic. These 22 intervals are not exactly the same as the 22 notes used in the 10 Thats of Indian Classical music. The Indian Classical music 22 note octave (called the Pure Tuning Octave) contains several complex fractional notes not found in the Just Intonation scale, and the just intonation scale has intervals not used in the 22 notes of the 10 Thats of India. More information on the10 Thats of India can be found at:  www.perfectthird.com

 

The Equal Temperament 12 note octave has none of the 22 pure tuning notes, however some are very close - within 2 cents. Others are as much as 14 cents sharp.

North Indian Classical Music - Raga

Ragas are the fundamental musical form for Classical Indian Music. According to Pandit Ravi Shankar the word Raga translates into English as "that which colors the mind".  There are many thousands of ragas. Some ragas have been played for thousands of years, and new ones are being composed constantly. All ragas come from the pure tuning 22 note octave. The 22 shrutis are the  source for the 10 X 8 note scales called the TEN THATS. Ragas are complex melodic and emotional vehicles for improvisation. They have parameters such as ascending and descending pathways, and particular sentiments for performance. Ragas have certain Intervals that are dominant and intervals called enemy notes.  They contain main intervals as their basic scale, and use many lesser intervals (called Shrutis) to add the mood color (Rasa). In the Hindustani (North Indian) Classical form the ragas have fixed times within the day when they can be performed, and some can only be performed during particular seasons of the year. The Carnatic classical music (South India) does not attach such rules as time of day, and use different intervals for Ragas of the same name in the northern form. Some Ragas have been associated with healing practices, some have been attributed with the ability to start fires or bring the rain.   It is claimed that the knowledge of ragas and the practice of Indian Classical Music can lead to enlightenment or Nirvana. So, the practice of Indian classical music is called a devotional yoga.

EQUAL TEMPERAMENT

Equal Temperament (ET) uses a 12 note octave which has been gradually adopted by western music to replace the pure tuning 22 note octave, (called Just Intonation or JI) Just Intonation revolves around a fixed tonal center and limits the modern concept of modulation.  The 12 ET notes are based on a mathematical formula that makes each of the 12 intervals the same distance apart on a decreasing scale.  The formula is:

The ET system of tuning allows each note to act as any interval within the octave,  giving modern music the ability to have sequential chord structures. Bach was one of the first to realize the potential of this system, and a full exploration of these principles is found in Bach's 12 Tone Inventions. Bebop to the Beatles, Beethoven to the Bangles all use the ET system.  The 22 Pure Tuning intervals are still used as passing tones which function as sweetening sounds in order to overcome the slightly sour sounds of some of the intervals of Equal Temperament.

 

 

 

Sympathetic string resonance

Sympathetic Resonance is the energy transference from a plucked main string attached to a bridge mounted on a resonant diaphragm, such as a guitar face.  The vibrations transfer into the harmonically related intervals of the sympathetic strings.

The Sympathetic Harp strings are similar to the sympathetic strings found on Indian stringed instruments, such as sitar and sarod. They are not played directly, but are instead driven or activated in response to the plucked main playing strings. These sympathetic vibrations activate the Jawari bridge and feed back into the guitar face, as well as generating an electric current in the micro-phonic elements within the Jawari bridge, which can then be amplified.
