A staff has five horizontal lines. Notes can sit on a line or in a space. Moving to the next line or space changes the letter name by one step. Higher on the page means higher pitch, not louder sound. Read time from left to right; notes stacked at the same horizontal position are played together.
A clef identifies the pitches of the lines. The treble clef curls around the second line from the bottom, G4. Its lines, bottom to top, are E4, G4, B4, D5, F5. Its spaces are F4, A4, C5, E5. Middle C4 sits on a short extra line below the staff, called a ledger line.
The treble illustration begins below the five-line staff and moves upward through C4, D4, E4, F4, and G4. Treat each line and each intervening space as a separate pitch position. Starting from the bottom line E4, the space immediately above is F4 and the next line is G4. Going down from E4 reaches D4 in the space below the staff, then C4 on its short ledger line. You do not need a separate rule for outside notes. The alternating sequence of spaces and lines continues beyond the five long lines.
Count changes of position rather than counting only staff lines. E4 to G4 crosses from one line to the next line, but it takes two letter steps because the F space lies between them. E4 to F4 takes one letter step because those positions touch in the line-and-space sequence. The drawing's equal vertical increments represent successive letter names, not fixed amounts of loudness or elapsed time. A high notehead is a pitch instruction. Its height does not ask you to play harder, wait longer, or choose a higher finger number.
Use the existing keyboard beneath the treble illustration to connect each staff position to a physical key. E4 is under finger 3 in the pictured right-hand position. F4 is immediately to its right under 4, and G4 is next under 5. On the staff these are line, space, line; at the keyboard they are three consecutive white keys. C4 and D4 remain part of the same route even though they sit below the main staff. Being outside the five long lines does not move a note to a different musical system.
Try locating the displayed F4 in two ways before playing. From E4 on the bottom line, move up to the neighboring space. From G4 on the second line, move down to the neighboring space. Both routes lead to F4. This is more reliable than judging whether a head looks close to the bottom of the drawing. If the routes disagree, recount the intervening positions. The staff has five lines regardless of the size of the SVG on your screen, so relative position is a better guide than pixel distance.
The bass clef's two dots surround the second line from the top, F3. Its lines, bottom to top, are G2, B2, D3, F3, A3. Its spaces are A2, C3, E3, G3. In piano music, treble is commonly used for the right hand and bass for the left, but clefs identify pitch, not which hand must play.
On natural-note examples, a step moves to an adjacent line or space, such as C to D. A skip passes over one letter, such as C to E. It moves from one line to the next line or one space to the next space. A repeated pitch stays at the same height. These describe letter distance; they do not yet tell you the number of semitones.
The same staff height means different pitches under different clefs. The bottom line is E4 in treble clef but G2 in bass clef. A notehead on a bottom line therefore does not identify a key until you know the clef. Read the clef before naming the first pitch of a staff. This matters when moving between the two illustrations on this page. Their similar five-line shapes invite you to reuse the treble names, but the bass example starts from a different reference and occupies a lower register.
The bass clef's dots identify F3 on the second line from the top. From that F, moving down one position reaches E3 in the space below. Moving down again reaches D3 on the middle line. Continue downward to C3 in a space and B2 on the second line from the bottom. This gives a route to the first displayed bass note, C3, without memorizing every line independently. Check the octave as well as the letter. C3 lies to the left of C4 on the keyboard and is a different pitch.
The bass illustration shows C3, D3, E3, F3, then C4. The first four ascend by neighboring staff positions. The final move does not continue by one position to G3. It goes beyond G3, A3, and B3 to C4, which needs a ledger line above the staff. On the accompanying keyboard, C3 and C4 mark opposite ends of the displayed octave. This is a concrete reason to inspect the last note's position rather than continuing a pattern you expected from the first four notes.
Treble and bass are pitch references, not permanent hand labels. The present course usually assigns the upper treble part to the right hand and the lower bass part to the left, but that is a choice in an arrangement. The bass illustration's C4 and the treble illustration's C4 identify one physical middle-C key. The change of clef changes where that pitch is written. It does not produce a second key that belongs exclusively to the other hand, and the octave digit does not change with the hand that plays it.
The practice figure E4, F4, G4, F4, E4 has a symmetric pitch path. Starting at the bottom treble line, move up to a space, up to a line, back down to the space, and back down to the starting line. With the right hand in the established C-through-G position, fingers 3, 4, 5, 4, 3 match that path. Read the starting landmark first, then follow the movement. If you begin on the wrong line, every later movement can have the correct direction while the entire passage uses wrong pitches.
A step in these natural-note examples moves from a line to its neighboring space or from a space to its neighboring line. A skip passes over one intervening letter. From E4 to G4, F is passed over and both noteheads sit on lines. From D4 to F4, E is passed over and both heads sit in spaces. Thus 'line to line' and 'space to space' describe the small skips being taught here. A larger jump can also begin and end on lines, so do not treat those words alone as a complete measurement of any possible jump.
Repeated notes need a different observation. Their heads stay at the same vertical position while time continues from left to right. In the melody from the previous lesson, the two opening Es share a height and still require two attacks. A shape-reading method that looks only for up or down can miss those repeats. Include 'same' as a possible next event. Then read the duration of each head separately. Repeated pitch does not tell you whether the next note has the same value, and a long note does not become repeated merely because several beats pass.
Use the practice figure for a prediction-and-check experiment. Cover its letter labels and name the first landmark. Describe the next movements in words before naming the remaining pitches. Then uncover the labels and compare each prediction with the figure. If a letter is wrong, check whether you misidentified the starting line or missed a line-to-space change. Those errors require different corrections. The figure contains five quarter notes as a pitch-reading example, so do not invent a four-beat bar boundary or alter a duration simply to force its five notes into one measure.
Start with treble E4 on the bottom line. Read E4, F4, G4, F4, E4 by following up one position, up one, down one, down one. Play with fingers 3, 4, 5, 4, 3. Then use bass F3, the line between the dots, to find E3 in the space below it.
A sharp, ♯, raises a written note by one semitone. A flat, ♭, lowers it by one semitone. A natural sign, ♮, cancels an accidental. An accidental normally affects that staff pitch for the rest of its measure; a key signature sets the default alterations across the piece. Our staff examples have no key signature and use only natural notes. Learn those first.
A note's staff position supplies its letter and octave under the clef. Its head, stem, flags, and dots supply duration. The finger number supplies a proposed action for a hand. These are independent pieces of information placed near one another. In the treble illustration, C4 through G4 all use filled heads with stems, so each has the same quarter-note value even though pitch rises. The keyboard picture explains their physical locations. It does not replace the note symbols as a source of rhythm or turn the pictured keys into a timed sequence.
Horizontal placement tells you the reading order of this single line, but the printed gaps are not a scale of seconds. A larger gap can leave room for labels, ledger lines, or a bar boundary. Read the note values to determine how much counted time passes. Similarly, the distance between two separate staff illustrations does not represent a musical interval. They are independent examples on the page. Comparing pitch requires reading each clef and its staff positions, not measuring the vertical gap between the figures with your eyes.
Ledger lines belong to the note's local staff. For middle C below treble, the short line crosses its notehead. D4 above that C occupies the space between the ledger line and the staff's bottom E line, so D does not need its own line through the head. In bass clef, middle C sits on the first ledger line above the staff. The space immediately below it is B3, just above the staff's top A3 line. These neighboring positions explain why the same C can be recognized without memorizing the empty page space around it.
When two noteheads share an attack position in a score, they can indicate simultaneous pitches rather than a fast left-to-right sequence. This page mainly uses successive single notes, so follow their order as printed. Do not infer that notes are simultaneous merely because separate teaching figures happen to align on your screen. Later combined-hand scores will explicitly organize parts together. For the present task, identify which illustration you are reading, which clef it uses, and which notehead follows the current one within that illustration.
The line-and-space method follows letter order, but adjacent letters do not always have the same keyboard distance. E4 to F4 and B3 to C4 have no intervening black key. C4 to D4 does have one. All three moves are letter steps on a natural-note staff. A semitone is the distance to the next physical key, black or white, so E to F is one semitone while C to D is two. The staff's one-position movement alone does not settle that distance. Use the keyboard pattern when you need to count physical-key intervals.
The accidental explanation in the practice section adds a separate instruction to a staff position. A sharp raises its written pitch by one semitone, and a flat lowers it by one. The notehead still occupies the same letter position on the staff. A natural sign returns that position to its natural form when an alteration needs cancelling. These symbols are not present in the natural-note staff figures. You can complete the current reading experiments without inventing altered notes or changing the fixed white-key assignments used for the examples.
If an accidental appears in a later score, reading the letter position remains necessary. The sign modifies that letter rather than replacing the need to identify it. Its usual within-measure effect also differs from a finger number, which gives an instruction at a note but does not alter later pitches. A bar line can reset the effect of a local accidental, while a key signature establishes defaults for the piece. This distinction explains why the clef and other symbols near the start of a staff deserve attention before you follow the notehead shape alone.
Finish by choosing one displayed note without its label and describing a complete route to it. For the bass E3, for example, identify the bass clef, find F3 between its dots, move down one position to the space, then locate E below F on the keyboard. For treble D4, start at the bottom E4 line and move down one position. If your named octave and physical key disagree, return to the reference pitch. A correct letter in the wrong octave is still a different note, even when the black-key pattern around it looks familiar.
In treble clef, name a note on the bottom line, then the space above it, then the next line.
The treble bottom line is E4, not C4.
The pitches are E4, F4, G4. A line, the space immediately above, and the next line form two upward steps. Use right-hand fingers 3, 4, 5 in the C-through-G position.
Is the C on the ledger line above the bass staff a different key from the C below the treble staff?
A clef changes how positions are named, not the keyboard's pitches.
Both are C4 and use the same key. The treble staff puts it below its five lines; the bass staff puts it above. The space between staves on a printed page may vary, so count staff positions and ledger lines rather than measuring the page gap.
Describe the movements in C4, E4, F4, E4.
A skip passes over one letter name.
C4 to E4 is an upward skip because D is passed over. E4 to F4 is an upward step. F4 to E4 is a downward step. On the staff, C and E are on adjacent lines; E and F are on a line and the neighboring space.
