* Khöömii is an amazing style of overtone/harmonic singing where one person sings two or more distinct pitches at the same time. It originates among the nomads of the central Asian plateau, particularly the Altai and Sayan mountain regions of Mongolia and Tuva. The nomads of these parts have discovered how to sing melodies that arise from the universal overtone or harmonic series. Listen to your own overtones as you discover the unknown depths and heights of your own voice through these enchanting sounds. <span class="plainlinks">[http://www.youtube.com/watch?v=gQUgtEBbPi4 Example : Khöömii]</span>
* The harmonium is an Indian instrument that is used as an accompaniment to chanting Sanskrit mantras. It is a keyboard instrument like a miniature organ which works with the use of bellows. These keep the air circulating through the banks of reeds inside. The harmonium can be played to create a tune or a continuous drone sound. The drone is particularly suited to accompany chanting or raga singing. In traditional Indian chanting the harmonium is accompanied by the tablas (Indian drums), which create a rhythm. The combined sound of voices chanting accompanied by harmonium and tabla creates a tremendous feeling of spiritual upliftment. <span class="plainlinks">[http://www.youtube.com/watch?v=PchEdezejZ8 Example : Manjit Singh (Gyaniji) Indian Classical Music - Harmonium, Tabla, and Vocal Teacher]</span>
* Raag is the ancient system of classical Indian Music, which can trace its roots back five thousand years. It combines the healing vowel sounds of ancient Sanskrit with particular groups of notes, sung in particular ways, which reflect the changes in the universe around us. This includes changes throughout the day and the changing seasons. By singing Raag we attune ourselves to the natural laws of sound, which are dynamic and life promoting. Raag means 'colour' and it is as if we are painting a picture of the natural world when we sing Raag. It is beautiful, sacred and one of the most truthful forms of music that I have come across. "The nearest thing to God" however we define that! The study of Raag brings a profound sense of connection and an appreciation of the mystery of life. <span class="plainlinks">[http://www.youtube.com/watch?v=oSEuCJSnu94 Example : Raag Yaman - Ustad Rashid Khan]</span>
