I'd love to learn how to play the piano, the acoustic stringed musical instrument! Can you play it?
The piano is an acoustic, stringed musical instrument invented in Italy by Bartolomeo Cristofori around the year 1700 (the exact year is uncertain), in which the strings are struck by hammers.

Piano
The piano is an acoustic, stringed musical instrument invented in Italy by Bartolomeo Cristofori around the year 1700 (the exact year is uncertain), in which the strings are struck by hammers. It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. The word "piano" is a shortened form of "pianoforte", the Italian term for the early 1700s versions of the instrument, which in turn derives from "gravicembalo col piano e forte" and "fortepiano". The Italian musical terms "piano" and "forte" indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the greater the velocity of a key press, the greater the force of the hammer hitting the strings, and the louder the sound of the note produced and the stronger the attack.
Mandolin
A mandolin ( ; literally "small mandola") is a stringed musical instrument in the lute family and is usually plucked with a plectrum or "pick". It commonly has four courses of doubled metal strings tuned in unison (8 strings), although five (10 strings) and six (12 strings) course versions also exist. The courses are normally tuned in a succession of perfect fifths. It is the soprano member of a family that includes the mandola, octave mandolin, mandocello and mandobass. There are many styles of mandolin, but three are common, the "Neapolitan" or "round-backed" mandolin, the "carved-top" mandolin and the "flat-backed" mandolin.
Musical instrument
A musical instrument is an instrument created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for ritual, such as a trumpet to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications.
Violin
The violin, also known informally as a fiddle, is a wooden string instrument in the violin family. Most violins have a hollow wooden body. It is the smallest and highest-pitched instrument in the family in regular use. Smaller violin-type instruments are known, including the violino piccolo and the kit violin, but these are virtually unused. The violin typically has four strings tuned in perfect fifths, and is most commonly played by drawing a bow across its strings, though it can also be played by plucking the strings with the fingers (pizzicato) and by striking the strings with the wooden side of the bow (col legno).
Electric guitar
An electric guitar is a guitar that uses one or more pickups to convert the vibration of its strings into electrical signals. The vibration occurs when a guitarist strums, plucks, fingerpicks, or taps the strings. The pickup used to sense the vibration generally uses electromagnetic induction to do so, though other technologies exist. In any case, the signal generated by an electric guitar is too weak to drive a loudspeaker, so it is sent to a guitar amplifier before being sent to the speaker, which converts it into audible sound. Since the output of an electric guitar is an electric signal, it can be electronically altered by to change the timbre of the sound.
Cello
The cello ( ; plural cellos or celli) or violoncello ( ; ) is a bowed, and sometimes plucked, string instrument with four strings tuned in perfect fifths. The strings from low to high are generally tuned to C, G, D and A, an octave lower than the viola. It is the bass member of the violin family of musical instruments, which also includes the violin, viola and the double bass. The cello is used as a solo musical instrument, as well as in chamber music ensembles (e.g., string quartet), string orchestras, as a member of the string section of symphony orchestras, and some types of rock bands. It is the second-largest and second lowest (in pitch) bowed string instrument in the modern symphony orchestra, the double bass being the largest and having the lowest (deepest) pitch.
Double bass
The double bass, or simply the bass (and numerous other names), is the largest and lowest-pitched bowed string instrument in the modern symphony orchestra. It is a transposing instrument and is typically notated one octave higher than tuned to avoid excessive ledger lines below the staff. The double bass is the only modern bowed string instrument that is tuned in fourths (like a viol), rather than fifths, with strings usually tuned to E, A, D and G. The instrument's exact lineage is still a matter of some debate, with scholars divided on whether the bass is derived from the viol or the violin family.

As a kid, I took lessons, and could play at a basic level, but the chords and how they connected never made sense to me, so I had to memorize sheet music.

Oh, I get that, it's just printed form of music notation so you're not really learning just replaying. Do you like music with piano in it?

Sheet music
Sheet music is a handwritten or printed form of music notation that uses modern musical symbols to indicate the pitches (melodies), rhythms or chords of a song or instrumental musical piece. Like its analogs – printed books or pamphlets in English, Arabic or other languages – the medium of sheet music typically is paper (or, in earlier centuries, papyrus or parchment), although the access to musical notation since the 1980s has included the presentation of musical notation on computer screens and the development of scorewriter computer programs that can notate a song or piece electronically, and, in some cases, "play back" the notated music using a synthesizer or virtual instruments.
Musical notation
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. 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 noteheads is the most common way of notating music, but for professional country music session musicians, the Nashville Number System is the main method.
Music
Music is an art form and cultural activity whose medium is sound organized 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.
Music theory
Music theory is the study of the practices and possibilities of music. "The Oxford Companion to Music" describes three interrelated uses of the term "music theory":  The first is what is otherwise called 'rudiments', currently taught as the elements of notation, of key signatures, of time signatures, of rhythmic notation, and so on. [...] The second is the study of writings about music from ancient times onwards. [...] The third is an area of current musicological study that seeks to define processes and general principles in music — a sphere of research that can be distinguished from analysis in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built.
Braille music
Braille music is a Braille code that allows music to be notated using Braille cells so music can be read by visually impaired musicians. The Braille music system was originally developed by Louis Braille. Braille music uses the same six-position Braille cell as literary braille. However braille music assigns a separate meaning to each braille symbol or group of symbols different from literary braille and has its own syntax and abbreviations. Almost anything that can be written in print music notation can be written in braille music notation. However, braille music notation is an independent and well-developed system with its own conventions.
Scorewriter
A scorewriter, or notation software or music notation processor, is software used with a computer for creating, editing and printing sheet music. A scorewriter is to music notation what a word processor is to word text, in that they both allow fast corrections (undo), flexible editing, easy sharing of electronic documents (via the Internet or compact storage media), and clean, uniform layout. In addition, most scorewriters, especially those from the 2000s, are able to "sound out" the notes using synthesizer instrument sounds or virtual instruments and record the notes (sound). This playback and recording feature is especially useful for novice composers or music students or when no musicians (particularly the very costly full orchestra) are readily available or affordable.
Music education
Music education is a field of study associated with the teaching and learning of music. It touches on all learning domains, including the psychomotor domain (the development of skills), the cognitive domain (the acquisition of knowledge), and, in particular and significant ways, the affective domain (the learner's willingness to receive, internalize, and share what is learned), including music appreciation and sensitivity. Music training from preschool through post-secondary education is common in most nations because involvement with music is considered a fundamental component of human culture and behavior.
