BECAUSE
Heart Strings
Are The Carriers Of
The Song Of Our Souls.
Zimmer is one of the biblical words for song. It is interesting that the well known singer-songwriter Bob Dylan’s given name is Robert Allen Zimmerman (Hebrew name אברהם בן זיסל שבתאי )
In Ephesians 5:19 we are to speak to one another in psalms, hymns and spiritual songs.
There is an art to speaking in songs.
It’s not a musical or on opera; but speaking in such a beautiful way that it could be a song. 
There is a no musical accompaniment when we speak, no melody or musical instrument.
To ‘speak in song’, means, all the words make up for the fact that there is no music and in themselves become a song that is so beautiful and harmonious, that they need no accompaniment.
Would our daily talk produce the transcript for a Godly song? Would it be a song of praise? Would it have words of love, peace and hope, thanksgiving, encouragement, mercy, courage and determination?
When we speak words like a song they make up for the fact there is no music.
We are encouraged to sing and make melody in our hearts to the Lord. Psalm 40:3; Ps 98:5; Judges 5:3;
Psalm 33:3. We are to sing to Him a new song; play skillfully, on the harp and shout for joy.
I will sing a new song to You, O God; Upon a harp of ten strings I will sing praises to You,Psalm 144:9
The word melody in Greek is psallo, which means, the pluck, as describes the way of playing a harp.
The word Psalm in Hebrew is,
mizmor
and a mizmor, is a piece of music, a praise played with an instrument to God.
Psallo, this word is specifically connected to making music on harp strings.
The Hebrew word mizmor eventually became psalmos and when the ancient Jewish scholars translated the Scriptures into the Greek language, the word psallo is where we get our word Psalm.
This reference indicates that if you want to praise God, you must play a musical instrument.
God has designed us physically to be able to do that, without any external instrument.
The instrument that produces music to the Lord, is our heart.
Let us sing to Him with the innocence childlike faith.
Our heart is like a harp, made to make holy music, if it is played right.
It’s a musical instrument and it’s at the center of your being, in the deepest part of your existence. That’s what makes the content of the music of praise to God and it originates from the deepest part of your being.
Hence the term or idiom, pulling on the heart strings, is often quoted for our heart is like a harp.
We look at life and our heart and often see that things don’t look so beautiful. Ups, downs, highs and lows, hopes and disappointment, joy, tears, love, rejection all jumbled together. Our hearts were never made to produce bitterness, hatred, fear, or depression. 
They were made to be instruments that make melody to the One who created them. The melody of praise and thanksgiving, the music of love, worship, joy and shalom. Psalm 33:1–5; Ephesians 5:19, 20;
A harp doesn’t just have one string but many. Some have
22 or 26
some 34
and 37 
and the concert grand harp has 47strings.
Both high and low strings just like the ups and downs in our lives and hearts. The highs give it brightness and brilliance and the lows give it deeper fuller sounds.
We have a secret harp right in the midst of our being and we are to praise Him in all of it and with all of it.
There’s a great beauty waiting to emerge from the highs and equally from the lows.
The key is to allow God’s Spirit, the Ruach ha Kodesh to touch all of the strings in your heart and make it beautiful and harmonious.
Allow Him to touch the joys, the high strings and also the low strings of sadness and hardship. What ever it is, as we bring it to the Lord, He will change it.
The touch of the Masters’ hand will cause that change. What ever we allow to be touched by the His hand, will be changed into heavenly MIZMOR.
Music carrying praises to Him.
The center of our being was created as an instrument to praise God, to be PSALLO, to be plucked, and when we do just that, our life will become a psalm, a song of praise, a MIZMOR to Him. 
Because He has put a new song in our hearts, we will pull it’s strings with deep joy. Composing a melody from within of worship, love and gratitude, in adoration for our Savior and the lover of our souls.
Allow Him to PLUCK the strings of our hearts; for the sound that comes forth will be straight from Heavens throne of glory.
Ephesians 5:19; Ecclesiastes 7:14.
On the Prayer Shawl or Tallit 
at each corner there are tzitzit 
and each of the 4 tzitzit have 8 strings, making a total of 32 strings.
Thirty-two is the numeric value of the Hebrew word for “HEART”.
LEBAB /LEB .
לֵבב
Phonetic Spelling: (lay-bawb) . inner man, mind, will, heart .
Mitral Heart Valves look like strings.
(Greek. kardia from where we get our word Cardiac.)
The tzitzit’s loose strings
represent
God’s ‘heart strings’ which are held on to tightly during prayer. 
Sound is all vibration, it is the impression produced on the ear by the vibrations of air.
The pitch of the musical note is higher or lower according as these vibrations are faster or slower. When they are too slow, or not sufficiently regular and continuous to make a musical sound, we call it noise.
Resonance – when a FORCED vibration matches an object’s natural frequency thus producing vibration, sound, or even damage. One example of this involves shattering a wine glass by hitting a musical note that is on the same frequency as the natural frequency of the glass. (Natural frequency depends on the size, shape, and composition of the object in question.) Because the frequencies resonate, or are in sync with one another, maximum energy transfer is possible.
Experiments have long been completed which fix the number of vibrations for each musical note; by which, of course, we may easily calculate the difference between the number of vibrations between each note.
The number of vibrations in a second, for each note, is a multiple of eleven, and the difference in the number of vibrations between each note is also a multiple of eleven.
The ear can detect and convey these vibrations to the brain only within certain limits.
Each ear has within it a minute organ, like a little harp, with about ten thousand strings.
When a sound is made, the corresponding string of this little harp vibrates in sympathy, and conveys the impression to the brain.The immense number of these little strings provides for the conveyance of every conceivable sound within certain limits. In the scale there is a range of 264 vibrations.
There is a difference between each one, so that there are practically 264 notes in the scale, but the ear cannot detect them.
The ear of a skilled violinist can detect many more than an ordinary untrained ear.
The mechanical action of a pianoforte can record only twelve of these notes.
The violin can be made to produce a much larger number, and is therefore more perfect as an instrument, but not equal in this respect to the human voice. The wonderful mechanism of the human voice, being created by God, far excels every instrument that man can make.
The same vocal chords that produce sounds that soothe, can also release a resonant frequency able to shatter glass.It is able to accomplish this, by matching the natural frequency of the crystal glass.
Frequency is calculated by dividing the speed with the wavelength. Therefore,
Frequency = speed / wavelength
Frequency = 340.29 m/s / 0.320 m
Frequency = 1063.41 /s
There are vibrations which the ear cannot detect, so slow as to make no audible sound, but there are ways by which they can be made visible to the eye.
When sand is thrown upon a thin metal disc, to which a chord is attached and caused to vibrate, (like a violin bow), the sand will immediately arrange itself in a perfect geometrical pattern.
The pattern will vary with the number of the vibrations. These are called “Chladni’s figures.” 
Moist plaster on glass or moist water-color on rigid surfaces will vibrate at the sound, say, of the human voice, or of a cornet, and will assume forms of various kinds—geometrical, vegetable and floral; some resembling ferns, others resembling leaves and shells, according to the pitch of the note.
The middle canal contains the basilar membrane, which holds the organ of Corti. The structure located in the cochlea that is the chief part of the ear, (middle ear), through which sound is perceived.
Named after Italian anatomist, Alfonso Giacomo Gaspare Corti, (1822–1876), who understood how God had created it.
Even the organs of Corti are limited in their perception, notwithstanding the many thousands of minute vibrating chords.
When these organs are perfect or well formed there is what is called “an ear for music.”
But in many cases there is “no ear for music.” This means that these organs are defective, not fully developed, or malformed, in the case of such persons; and that the sounds are not accurately conveyed to the brain.
There is a solemn and important truth therefore in the words, “He that planted the ear”! (Psa 94:9). What a planting and what an amazing God who created all these things, most of which we will never see! Even when we don’t ‘see the sounds’, they are still creating patterns in the very air around us. Helps to better understand the saying, ‘Creating an atmosphere!’
Not every one has this peculiar (musical) “ear.”
And no one has by nature, that ear which can distinguish the things of God.
The spiritual ear is the direct gift and planting of God. Hence it is written, “He that hath an ear,” i.e., only he that hath that divinely-planted, God-given ear can hear the things of the Spirit of God. “An ear to hear” those spiritual things is a far greater reality, and an infinitely greater gift, than an ear for music!
Oh wondrous ear! It is the Lord that gives “the hearing ear” (Prov 20:12). 
He wakeneth the ear to hear (Isa 50:4);
It is the Lord that openeth the ear (Isa 50:5). 
The natural ear does not hear spiritual sounds; it cannot discern them. (Isa 64:4 and 1 Cor 2:9). 
Thus nature and grace illustrate each other, and reveal the great fact that there is a secret ear, more delicate than any “organs of Corti,” that can detect sounds invisible as well as inaudible to the senses, and which enables those who possess it to say:—
“Sweeter sounds than music knows
Charm me in Emanuel’s name;
All her hopes my spirit owes
To His birth, and cross, and shame.”
The biblical history of the harp goes back to the antediluvian era when the House of Jubal was known as the maker and players of harps and the flutes. (Gen. 2:40)
A sheqel coin with a harp as part if the design.
The first recorded harp in ancient historical records was in the Sumerian and the Ancient Egyptian societies.
The most famous harp in history is the Harp of David. This harp was a symmetrical harp known as the Kinnor Harp.
What we now know is this Mishnah is that David was not only an expert harpist and psalms composer, who used harp therapy in the royal court of King Saul, 
but was also a recognized musicologist and builder of classical harp designs.
Beside the Kinnor / lyre
kinnor: a lyre כִּנּוֹר 
or the Harp of David,
The nevel or nebel
(Hebrew: נֵ֤בֶל nêḇel)
the Nevel/ Harp, most popular as a ten stringed lap harp.
Yet the most complex and mystical of the Nevel Harps was the twenty-two stringed Nevel Harp
which was recognized by some rabbinic sources to produce the most perfect of music.
According to the traditions of the Jews, the Lord of hosts used a twenty-two stringed heavenly harp called the Nevel in the creation of this earth.
The transcendent energy of the twenty two frequencies became the Hebrew language with twenty-two letters from alef to tav and formed the energy matrix of this earth. 
For believers there are specific jobs of service, to be carried out with the greatest “Kavanah” (Divine Intention), and the purest vibrations of the heart.
Let the melody in your heart become your zimmer talk.
There may be more than we realize to the turn of phrase, ‘singing your heart out’ because heart strings are the carriers of the song of our souls!
Shalom!
