input: Please answer the following: Information:  - A quarter note ( American ) or crotchet ( British , from the sense ' hook ' ) is a note played for one quarter of the duration of a whole note ( or semibreve ) . Often , musicians will say that a crotchet is one beat , but this is not always correct , as the beat is indicated by the time signature of the music ; a x quarter note may or may not be the beat . Quarter notes are notated with a filled - in oval note head and a straight , flagless stem . The stem usually points upwards if it is below the middle line of the stave or downwards if it is on or above the middle line . However , the stem direction may differentiate more than one part . The head of the note also reverses its orientation in relation to the stem . ( See image . )  - In musical notation, a key signature is a set of sharp, flat, and rarely, natural symbols placed together on the staff. Key signatures are generally written immediately after the clef at the beginning of a line of musical notation, although they can appear in other parts of a score, notably after a double barline.  - The time signature (also known as meter signature, metre signature, or measure signature) is a notational convention used in Western musical notation to specify how many beats (pulses) are to be contained in each bar and which note value is to be given one beat. In a musical score, the time signature appears at the beginning of the piece, as a time symbol or stacked numerals, such as or (read "common time" and "three-four time", respectively), immediately following the key signature or immediately following the clef symbol if the key signature is empty. A mid-score time signature, usually immediately following a barline, indicates a change of meter.  - In music, a half note (American) or minim (British) is a note played for half the duration of a whole note (or semibreve) and twice the duration of a quarter note (or crotchet). It was given its Latin name ("minim", meaning "least or smallest") because it was the shortest of the five note values used in early medieval music notation . In time signatures with 4 as the bottom number, such as or time, the half note is two beats long. However, when 2 is the bottom number (including "alla breve"), the half note is one beat long.  - A clef (from French: "clef" "key") is a musical symbol used to indicate the pitch of written notes. Placed on one of the lines at the beginning of the stave, it indicates the name and pitch of the notes on that line. This line serves as a reference point by which the names of the notes on any other line or space of the stave may be determined. Only one clef that references a note in a space rather than on a line has ever been used.  - In music notation, a note value indicates the relative duration of a note, using the color or shape of the "note head", the presence or absence of a "stem", and the presence or absence of "flags/beams/hooks/tails".  - In music, a whole note (American) or semibreve (British) is a note represented by a hollow oval note head and no note stem. Its length is equal to four beats in time, that is the whole measure (or bar). Most other notes are fractions of the whole note (e.g., half notes and quarter notes are played for one half and one quarter the duration of the whole note, respectively).  - Music is an art form and cultural activity whose medium is sound and silence, which exist in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek  ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."  - Music notation or musical notation is any system used to visually represent aurally perceived music played with instruments or sung by the human voice through the use of written, printed, or otherwise-produced symbols, including ancient symbols or modern musical symbols and including ancient symbols cut into stone, made in clay tablets or made using a pen on papyrus, parchment or manuscript paper; printed using a printing press (ca. 1400s), a computer printer (ca. 1980s) or other printing or modern copying technology. Types and methods of notation have varied between cultures and throughout history, and much information about ancient music notation is fragmentary. Even in the same time period, such as in the 2010s, different styles of music and different cultures use different music notation methods; for example, for professional classical music performers, sheet music using staves and note heads is the most common way of notating music, but for professional country music session musicians, the Nashville Number System is the main method.

In Story mode, it begins with the problems of Riley Harlow and Vince Moore. Rewards are unlocked as set goals are achieved. In the open-ended Classic mode, the player creates Sims and then chooses how they'll live their life. "The Sims Life Stories" was released on February 6, 2007. It is categorized as laptop-friendly since it lacks the need for an independent graphic card.  - The Sims 2 is a 2004 strategic life simulation video game developed by Maxis and published by Electronic Arts. It is the sequel to the best-selling computer game "The Sims".  - A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word "video" in "video game" traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images. Some theorists categorize video games as an art form, but this designation is controversial.    Given the information, choose the subject and object entities that have the relation of 'developer'.
