What an arpeggio is
An arpeggio plays the notes of a chord one at a time instead of all together. A seventh chord arpeggio has four notes: root, third, fifth, and seventh. In C major seventh those are C, E, G, and B. Arpeggios are the bridge between chords and solos: they outline the harmony exactly, so a solo built from arpeggios always fits the chords underneath. Jazz, country, metal, and prog solos all lean on arpeggios, and this tool shows the two pattern families you need.
How to use the finder
Pick a chord root, a seventh chord type, and a pattern. Position shapes show every chord tone inside a small fret window, with the root on the sixth or fifth string. Root notes are marked in orange. Sweep shapes show one note per string, ascending from the low string to the high string, which is the shape used for fast sweep picking. Start with position shapes: they teach you where the chord tones live. Add sweep shapes once you can find the chord tones without hunting.
Position shapes first
A position shape is a map, not a lick. It shows all four chord tones within four frets, so you can build phrases anywhere inside the window. Practise a position shape by playing the chord tones in order, then in broken patterns: root, third, fifth, seventh, fifth, third. Then play the same shape over a backing track and land on the root at the end of each bar. When the shape feels like home, move it to a new root: the shape moves with the root, so one pattern gives you all twelve keys.
Sweep shapes honestly explained
Sweep picking plays one note per string with a single smooth pick stroke, which makes fast arpeggios possible. It looks impressive and it is genuinely hard: each string must be muted just after it sounds, or the notes blur into a chord. The sweep shape in this tool ascends across the strings with the closest available fret on each string, which keeps the hand movement small. Practise sweeps slowly with a metronome and a clean tone first. Speed without muting sounds messy, and a clean slow sweep impresses listeners more than a fast blurry one.
Which seventh chord is which
Major seventh chords sound dreamy and settled: root, major third, fifth, major seventh. Minor seventh chords sound mellow and soft: root, minor third, fifth, minor seventh. Dominant seventh chords sound tense and ready to resolve: root, major third, fifth, minor seventh. Half-diminished seventh chords sound dark and unstable: root, minor third, flat fifth, minor seventh. The finder covers all four, because songs mix them constantly. Learn to hear the difference between major seventh and dominant seventh first: it is the single most useful ear skill in harmony.
Putting arpeggios into solos
Do not run arpeggios up and down as an exercise and call it a solo. Use them as targets: play a scale phrase, then land on a chord tone from the arpeggio when the chord changes. That one habit makes solos sound intentional. Practise over a two-chord loop, for example Am7 to D7, switching arpeggio shapes at each chord change. Start with one position shape per chord, then add the sweep shape for one chord only. Your solos will start to follow the song instead of floating over it, and listeners will hear the difference immediately.
Arpeggios in rhythm playing
Arpeggios are not only for solos. Rhythm players use broken chord patterns to create movement under a singer without strumming full chords. A gentle arpeggio pattern on an acoustic guitar can carry a whole verse, and the same pattern on an electric guitar with delay sounds huge. Practise arpeggios with a pick and with fingers: fingerpicking gives each note its own attack and makes the pattern breathe, while a pick gives a sharper, more even line.
