Mirabai had sung this:
Sister, the sound of the flute
Has driven me crazy.
Without Hari, nothing avails
On hearing the sounds
I lose body-consciousness,      
My heart well caught in the meshes of the net.
The magic of those seven notes
Has entrapped even Mira’s Lord Himself
-The Devotional Poems of Mirabai translated by A.J.Alston
Also this :
On the banks of the Yamuna
The flute was heard.
The Flute-Player has captured my heart,
My soul has no strength to withstand.
Dark Himself,
Krishna is seated on a dark blanket
By the dark waters of the Yamuna.
On hearing the sounds of the flute
I lose body consciousness,
My body remaining like a stone
-The Devotional Poems of Mirabai translated by A.J.Alston
Kabir had said this:
The middle region of the sky,
Wherein the spirit dwelleth, is
Radiant with the music of  light;
There, where the pure and white music
Blossoms, my Lord takes his delight.
In the wondrous effulgence of each hair       
Of His body, the brightness of millions
Of  suns and of moons is lost.
On that shore there is a city, where the
Rain of nectar pours and pours, and
Never ceases.
-Translation of Rabindranath Tagore
The Sound by which the heart is pierced - that tremendous Sound went on sounding from the Muladhar to the Brahmarandhra.
- Lahiri Mahasay’s Gita Commentary, Chapter 1, Verse 19, English Translation and Copyright, Yoga Niketan Inc
Remaining always and constantly in the Omkar Sound, one is stilled and attains yoga - therefore, just listen to the Omkar Sound.
- Lahiri Mahasay’s Gita Commentary, Chapter 2, Verse 53, English Translation and Copyright, Yoga Niketan Inc
The type of sound that is heard by the ears after the second quarter of the night, when all is silent - ch(n)oooooooo,* through the special practice of Kriya by the Grace of Sadguru, when, being filled with inner experience, consciousness is stilled, that kind of an unearthly sound - O(N)OOOOOOOOONG** - is heard.  This is the evidence of the stilling of consciousness.  When this is sounded within, certain mudras, meaning, indications appear outside.  Seeing these, sages recognize each other.  These signs are extremely secret.  One can become aware of them through Guru.  Without such stilling of consciousness, manifesting Supreme Awareness and the consequent growth of the power of internal knowing, the meaning of the Vedas is not internalized in the heart.
