Johann Bach

Johann Sebastian Bach (21 March 1685, O.S.31 March 1685, N.S. – 28 July 1750, N.S.) was a German composer, organist, harpsichordist, violist, and violinist whose sacred and secular works for choir, orchestra, and solo instruments drew together the strands of the Baroque period and brought it to its ultimate maturity. Although he did not introduce new forms, he enriched the prevailing German style with a robust contrapuntal technique, an unrivalled control of harmonic and motivic organisation, and the adaptation of rhythms, forms and textures from abroad, particularly from Italy and France.

Revered for their intellectual depth, technical command and artistic beauty, Bach's works include the Brandenburg Concertos, the Goldberg Variations, the Partitas, The Well-Tempered Clavier, the Mass in B minor, the St Matthew Passion, the St John Passion, the Magnificat, the Musical Offering, The Art of Fugue, the English and French Suites, the Sonatas and Partitas for solo violin, the Cello Suites, more than 200 surviving cantatas, and a similar number of organ works, including the famous Toccata and Fugue in D minor and Passacaglia and Fugue in C minor, and the Great Eighteen Chorale Preludes and Organ Mass.

Bach's abilities as an organist were highly respected throughout Europe during his lifetime, although he was not widely recognised as a great composer until a revival of interest and performances of his music in the first half of the 19th century. He is now generally regarded as one of the main composers of the Baroque style, and as one of the greatest composers of all time.

GRAND PIANO

The piano is a musical instrument played by means of a keyboard. It is widely known as one of the most popular instruments in the world. Widely used in Classical music for solo performances, ensemble use, chamber music, andaccompaniment, the piano is also very popular as an aid to composing and rehearsal. Although not portable and often expensive, the piano's versatility and ubiquity have made it one of the world's most familiar musical instruments.

Pressing a key on the piano's keyboard causes a felt-covered hammer to strike steel strings. The hammers rebound, allowing the strings to continue vibrating at their resonant frequency. These vibrations are transmitted through a bridge to a sounding board that couples the acoustic energy to the air so that it can be heard as sound. When the key is released, a damper stops the string's vibration. See the article on Piano key frequenciesfor a picture of the piano keyboard and the location of middle-C. According to the Hornbostel-Sachs method of music classification, pianos are grouped with chordophones.

The word piano is a shortened form of the word pianoforte, which derives from the original Italian name for the instrument, clavicembalo [or gravicembalo] col piano e forte (literally harpsichord capable of playing at the normal level, or more strongly). The musical terms "piano" and "forte" are usually interpreted as "soft" and "loud", but this is not strictly what they mean in Italian. "Piano" means here a plane or level, suggesting the normal level of playing. "Forte" would mean a stronger, more powerful level of playing, effectively louder than usual. This refers to the instrument's responsiveness to keyboard touch, which allows the pianist to produce notes at different dynamic levels by controlling the speed with which the hammers hit the strings.

A harp is a stringed instrument which has the plane of its strings positioned perpendicular to the soundboard. It is classified as a chordophone by the Harvard Dictionary of Music and only types of harps are in that class of instruments with plucked strings. All harps have a neck, resonator, and strings. Some, known as frame harps, also have a forepillar; those lacking the forepillar are referred to as open harps. Depending on its size (which varies considerably), a harp may be played while held in the lap or while it stands on the floor. Harp strings are made of nylon, gut, wire, or silk on certain instruments. A person who plays the harp is called a harpist orharper. Folk musicians often use the term "harper", whereas classical musicians use "harpist".

Various types of harps are found in Africa, Europe, North, and South America, and in Asia. In antiquity, harps and the closely related lyres were very prominent in nearly all cultures. The oldest harps found thus far have been uncovered in ruins from ancient Sumer. The harp also predominant in the hands of medieval bards, troubadors and minnesingers, as well as throughout the Spanish Empire. Harps continued to grow in popularity through improvements in their design and construction through the beginning of the twentieth century.

The aeolian harp (wind harp), the autoharp, and all forms of the lyre and Kithara are not harps because their strings are not perpendicular to the soundboard; they are part of the zither family of instruments along with thepiano and harpsichord. In blues music, the harmonica is called a "Blues harp" or "harp", but it is a free reedwind instrument, not a stringed instrument, and is therefore not an actual harp.
