Continue here when you can find C through G and count a four-beat bar. The first six lessons introduced individual notes. Now read groups: a starting landmark followed by repeated notes, steps, and larger distances. Keep the note-name labels on for a first attempt, then hide them without hiding the finger numbers.
An interval describes the distance between two pitches. For its number, count letter names inclusively. C to D is a second: C, D. C to E is a third: C, D, E. C to G is a fifth. A repeated C is a unison. The interval number is not the number of semitones; C to E and E to G are both thirds, but the former has four semitones and the latter three.
Seconds, thirds, and a fifth
Right hand · treble clef. Finger numbers: 1 thumb, 2 index, 3 middle, 4 ring, 5 little.
Read each pair separately. A second changes line to neighboring space; a third moves line to next line or space to next space. A fifth spans five letter names including both endpoints.
Keep interval numbers separate from semitone counts
The opening comparison score has three pairs. C4 to D4 is followed by a return to C4 and a move to E4. A final C4 is followed by G4. Read each pair from its own C rather than treat all six notes as one continuously expanding interval. The first pair is a second, the next a third, and the last a fifth. Their fingerings in this right-hand position are 1 to 2, 1 to 3, and 1 to 5. These numbers happen to match the interval numbers because of this particular starting position.
Count letters to explain each number. For C to G, count C as one, D as two, E as three, F as four, and G as five. There are four moves between neighboring letter names, but five letters including the endpoints. A repeated C to C is a unison, not a second, because there is only one letter position involved. Use this inclusive count consistently. Otherwise a fifth may seem to have the wrong number merely because you counted movements instead of the two endpoints.
Compare that method with the keyboard distances from the chord lesson. C to E spans four semitones, but its interval number is three. E to G spans three semitones, and its interval number is also three. Interval numbers classify letter distance. Semitones measure the smaller pitch distances between adjacent keys. Neither count replaces the other. At this stage, recognize seconds, thirds, and fifths in these natural-note examples without assuming that every third has the same exact sound distance.
You can check the distinction without playing. Point to C4 and E4 in the second pair of the first score. Then compare that same E4 with the G4 at the end of the third pair. Both letter pairs omit one intervening letter. C to E spans four semitones, while E to G spans three because E to F is only one semitone. The absence of a black key between E and F explains the unequal totals. This gives a concrete reason to keep the staff's letter-based counting separate from the keyboard's semitone counting.
A note on a ledger line is part of the same sequence. Do not restart your counting at the edge of the staff. In the treble clef, C4 is the ledger line below, D4 the space below, and E4 the bottom staff line. From E4, a third up is G4 on the next line.
Stopped. Select a note with Next note, or play with sound.
Right hand · treble clef. Finger numbers: 1 thumb, 2 index, 3 middle, 4 ring, 5 little.
Tempo: 60 quarter-note beats per minute. The count-in lasts 4 beats. Durations in the selected-note readout use quarter-note units. Tempo changes and Reset stop playback and select the first note. Audio starts only on request, plays once, and stops when hidden or off-screen. The tones are synthesized pitch guides, not a piano recording. A short release gap separates notes. Next note advances to the next attack in either hand. Held notes stay highlighted. There is no moving cursor. Start at low device volume.
The first four notes are C, E, D, F. Their movements are up a third, down a second, up a third. In the initial C-to-G hand position, the finger sequence is 1, 3, 2, 4. Interval reading tells you where to move; fingering tells you which finger to use.
Use line and space changes as evidence
A staff step moves from a line to its neighboring space or from a space to its neighboring line. A third moves from one line to the next line, or one space to the next space. The unchanged line-or-space type is useful evidence, but it does not identify every interval. A fifth also moves line to line or space to space, with more positions between. Count how far the note moved rather than conclude that every pair of notes on lines forms a third.
Use middle C4 as an example at the edge of the treble staff. Its ledger line is a continuation of the same pattern. Above it are D4 in a space, E4 on the bottom staff line, F4 in a space, and G4 on the next line. C to E and E to G are successive thirds. C to G is a fifth because the entire route includes five letter positions. The ledger line is not a separate category of note that interrupts this count.
A descending interval uses the same inclusive method in the opposite direction. From F4 down to D4, count F, E, D. Both endpoints occupy spaces, and E lies between them on the bottom line. From D4 down to C4, count D, C, which is a second. If the low note seems unfamiliar because it is outside the five main lines, continue the sequence downward. Do not move the note up an octave just to place it inside the staff.
For a visual check, hide the optional names in the two-bar phrase and describe only the directions and sizes before playing. Then restore the labels and verify your account. A line-to-line movement that you called a second cannot be correct in these examples. A same-height movement that you called a third also needs reinspection. These checks catch some errors without requiring immediate recall of every staff note. They do not replace the starting landmark, since an accurate shape read from the wrong initial pitch would transpose the whole phrase.
Staff direction and stem direction answer different questions. A stem may point up or down for engraving clarity; the notehead's vertical position still determines pitch. Compare the bass phrase's higher notes with its opening C and follow the heads rather than the ends of the stems. A downward-pointing stem does not instruct a descending interval. Likewise, a finger number printed below the bass staff does not lower the note. These marks occupy different places so that the pitch, duration, and playing instructions remain readable together.
Work through the right-hand phrase in complete bars
The right-hand phrase begins C4, E4, D4, F4, each for one beat. Read C on its ledger line, then move up a third to the bottom-line E. Move down a second to D in the space below that line. Move up a third to F in the bottom staff space. The printed fingers 1, 3, 2, 4 follow those destinations in the original five-note position. In particular, the second upward third ends on F rather than repeat the earlier destination E.
Bar 2 begins E4, continues D4, and ends C4 held for two beats. The transition from the last F of bar 1 to E is a downward second across the bar line. The next two movements are downward seconds as well. The bar line does not reset the hand position or change the distance rule. It groups the rhythm into four beats. Keep the final C through counts 3 and 4, then finish at the boundary where a following bar's 1 would begin.
There are seven attacks across eight beats. The first bar contributes four attacks and four beats. The second contributes three attacks but still four beats because the final note lasts two. This difference matters when using Next note. Seven selections do not imply seven equal pulses or a seven-beat phrase. The final selected C represents the whole two-beat ending. Read its open notehead and stem rather than infer duration from the number of selections or from the visual gap after it.
Try naming each destination from the preceding note instead of reading every optional label in isolation. Say C, up a third to E, down a second to D, up a third to F. Continue through the bar boundary before playing. Then compare that reasoning with the finger sequence. If you reach G after D, you have moved too far. If you reach E instead of F, you may have recalled the earlier C-to-E pair rather than counted from the current D. That is a reading error, even if the hand found a familiar key.
Read once before playing
Without sound, name the starting note, meter, and longest note. Point out a repeated pitch, step, or skip where one occurs.
Tap and count the rhythm before playing the pitches. Plan the fingers over C through G.
Play at 60 BPM without restarting for every error. Note where you lost your place.
Practice that transition, then hide the optional labels for a fresh attempt.
Sight-reading means playing unfamiliar music from notation. Once you know this phrase by memory, repeating it is useful practice but no longer a fresh sight-reading test. Use the new bass-clef phrase below as a separate reading attempt. Place left-hand 5 on C3, 4 on D3, 3 on E3, 2 on F3, and 1 on G3.
Stopped. Select a note with Next note, or play with sound.
Left hand · bass clef. Finger numbers: 1 thumb, 2 index, 3 middle, 4 ring, 5 little.
Tempo: 60 quarter-note beats per minute. The count-in lasts 4 beats. Durations in the selected-note readout use quarter-note units. Tempo changes and Reset stop playback and select the first note. Audio starts only on request, plays once, and stops when hidden or off-screen. The tones are synthesized pitch guides, not a piano recording. A short release gap separates notes. Next note advances to the next attack in either hand. Held notes stay highlighted. There is no moving cursor. Start at low device volume.
Let the bass clef change the landmark, not the method
The separate left-hand phrase is a new reading attempt, not a lower replay of the upper phrase. In bass clef, C3 lies in the second space from the bottom. E3 is in the next space above it, and G3 in the next space above that. These are thirds upward. The first bar therefore goes C3, E3, G3, with the last note held for two beats. Its pitches share a familiar chord collection, but the score presents them successively rather than as a stacked chord.
The left-hand finger sequence decreases while pitch rises. Finger 5 starts C3, finger 3 plays E3, and thumb 1 plays G3. The hand has not changed the meaning of any number. Both thumbs are still 1 and both little fingers are still 5. What changes is their left-to-right arrangement over the keyboard. In the initial left-hand position, the little finger occupies the low end and the thumb the high end. Rising pitch therefore does not imply a rising finger number.
Read the second bar before trying it. From G3, move down a second to F3 on the line between the bass-clef dots. Then move down a third to D3 on the next lower line. Finally move down a second to C3 in the space below D. The fingers are 2, 4, 5 for F, D, C. The last C lasts two beats. This bar is different from the treble phrase's E, D, C ending, even though both finish with a two-beat C.
A useful separate-hand experiment is to find F3 from the bass-clef landmark first, then read backward toward the preceding G3 and forward toward D3. This checks the route from a note inside the phrase rather than always depend on the opening C. If you name F correctly but choose the wrong key, verify the octave and black-key group at the instrument. If the key is right but the finger is wrong, consult the printed assignment. Interval recognition, keyboard location, and fingering are related decisions, but one correct decision does not establish all the others.
Read ahead without replacing the score with memory
The two players offer different reading tasks, so inspect the bass example before hearing it if you want an unfamiliar attempt. Once playback has supplied its pitches, the task includes recall as well as reading. That is still useful practice, but it is no longer the same test. The same applies when the right-hand phrase becomes familiar through repetition. Accurate performance then shows that you can reproduce this phrase; it does not alone show that you can decode a different score.
Reading ahead can be very small. While holding the final G of the bass phrase's first bar, identify the coming F and its finger 2. You have two counted beats on G during which to inspect that destination. Do not shorten G because you have already recognized the next note. The written duration gives time for preparation while the sound continues. This is a different action from jumping your eyes several bars forward or trying to memorize the entire page before moving.
When a mistake occurs, distinguish the first wrong note from later consequences. Starting the treble phrase on D instead of C may shift every subsequent shape while preserving their directions. Starting correctly but making D-to-F into D-to-E changes one interval and can shift later reading. Losing the count on the final half note is a duration problem even if every pitch is correct. Compare the first discrepancy with the static score, then practice a short approach into that note rather than correct several symptoms at once.
For a final silent check, use the displayed scores to find a second that crosses a bar line, a third whose endpoints are spaces, and a two-beat ending. Explain why each qualifies before using sound. The treble F-to-E boundary supplies the first, and the bass C-to-E beginning supplies the second. Both phrases supply the last. These examples require different evidence: neighboring letter positions, one skipped letter, and an open notehead with a stem. Keeping those kinds of evidence distinct makes your reading explainable rather than a guess based on the overall outline.
Exercises
Name the interval, not the key count
What are the interval numbers from C to E and from C to G?
Hint
Count C as one when counting letter names.
Worked answer
Read the answer on the staff
Right hand · treble clef. Finger numbers: 1 thumb, 2 index, 3 middle, 4 ring, 5 little.
Two pairs: C–E, then C–G.
C to E is a third; C to G is a fifth. On white keys, the moves are two and four neighboring-key steps respectively, but interval numbers count both endpoints. Do not call C to E a second just because you moved twice.
Read down from a landmark
Start on G4. Move down a third, then down a second. Which notes and fingers follow?
Hint
Treble G4 is on the second line from the bottom. A third down passes through F.
Worked answer

Right hand · treble clef. Finger numbers: 1 thumb, 2 index, 3 middle, 4 ring, 5 little.
G to E is a third down; E to D is a second down.
A third below G4 is E4, on the bottom line. A second below E4 is D4, in the space below. Play G–E–D with right-hand fingers 5–3–2 in the starting position. These are different distances, not three consecutive white keys.
Read the bass phrase independently
Read the first bar of the bass example. Why does its fingering go 5–3–1 rather than 1–3–5?
Hint
Left-hand finger numbers run in the opposite spatial direction from the right hand.
Worked answer

Left hand · bass clef. Finger numbers: 1 thumb, 2 index, 3 middle, 4 ring, 5 little.
A third up, another third up, and a two-beat hold.
The first bar is C3, E3, G3 with fingers 5, 3, 1. The right hand would use 1, 3, 5 in its similar C-position shape. Both thumbs are finger 1, but the left thumb is at the high end of this left-hand position. Hold G for beats 3 and 4.
